In particular, the central bank, charged with controlling inflation, cannot use taxation to reduce the money supply, because banks do not get to set tax policy. That leaves raising interest rates as its only policy tool.

As the political arm of the government chooses to run deficits in excess of growth plus inflation, then (a) that causes more inflation, and (b) the central bank raises rates, increasing the cost of government borrowing, causing bigger deficits.

This escalates as a result of the central bank trying to control the effects of high government spending by applying a mis-matched policy tool (interest rates) in place of the politicians who have abdicated their responsibility to use a matched policy tool (taxation). Either it spirals out of control, or more and more of the government budget is devoted to interest expense (direct government transfers of wealth paid exclusively to the debt holders) and less of it is spent on providing actual government services (that benefit all taxpayers).

If the central bank does not raise rates, of course, things go even more badly.

> I've seen many discussions stating patent hoarding has gone too far...

Vibe coding does not solve this problem. If anything, it makes it worse, since you no longer have any idea if an implementation might read on someone else's patent, since you did not write it.

If your agent could go read all of the patents and then avoid them in its implementations and/or tell you where you might be infringing them (without hallucinating), that would be valuable. It still would not solve the inherent problems of vagueness in the boundaries of the property rights that patents confer (which may require expensive litigation to clarify definitively) or people playing games with continuations to rewrite claim language and explicitly move those boundaries years later, among other dubious but routine practices, but it would be something.

derf_··on Why poor countries stopped catching up
This is the standard advice from the World Bank, the IMF, etc., and it does developing countries a huge disservice. South Korea banned the import of foreign cars from 1968 to 1988 while it developed its own automobile industry (Japanese imports were banned until 1998). Now Huyndai Motor Group sells more cars than GM [0]. That firm absolutely could not have survived if exposed to the ravages of the free market during the two decades it took them to learn how to produce cars to a globally competitive level. There are many other examples of protectionism in the developmental success that is South Korea. The idea ("infant industry protection") comes from Alexander Hamilton. The US relied on it heavily, too, in its early history.

If South Korea had followed the standard developmental economists' advice they would still be sewing garments and growing soybeans instead of manufacturing semiconductors, consumer electronics, and appliances (among many other things).

> The stock market is mostly just an inverse of currency health and tends to be inline or slightly above inflation on average...

This is demonstrably false? Long-term average US inflation since 1913 is 3.1% [0]. Long-term nominal average US stock returns since 1928 are 9.94% [1]. A nearly 7% advantage compounded every year for roughly a century is not "slightly above", it is absolutely enormous. Over 60,000% enormous.

Furthermore, when inflation is high, interest rates go up, and interest rates act like gravity on stock prices. See any number of Warren Buffett shareholder letters. See also: the year 2022. Stock market returns are mildly negatively correlated with inflation (with a coefficient of -0.229 [2]).

This will continue to happen as long as it is effectively unpunished. Even retracting the paper would do little good, as odds are it would not have been written if the author could not have used an LLM, so they are no worse off for having tried. Scientific publications are mostly a numbers game at this point. It is just one more example of a situation where behaving badly is much cheaper than policing bad behavior, and until incentives are changed to account for that, it will only get worse.

All of those are true, yet the US's (PPP-adjusted) per capita GDP was over 37% higher than the EU's in 2024 [0], and GDP growth has significantly outpaced the EU for years. Basically, whenever there was a choice between anything and economic growth, the US chose growth. Other places made different choices. You can argue about which choices were better, and how the results are distributed, but the difference in salaries for most people using this site are even more stark.

derf_··on What happened to all the gold Spain got from the New World? (1985)
You can, but then those people have more money, and you have less. The money supply is much smaller than the supply of goods and services, because the same money circulates repeatedly. So simply doubling your money can tilt things a little more your way, but does not make the situation completely lopsided, because you can only spend the extra money once.

Also, to quote Jastram [0], "In spite of the romanticism of the Spanish Main and treasure ships, the supply of gold from the New World was just a trickle by later standards. Less than 1% of what was to be 1930 world production was produced in each of the years from 1500 to 1520." Over the next 80 years, it never got much above 1.3%.

derf_··on Anatomy of US inequality
You make it sound easy, but there are relatively few billionaires in the US descended from historically wealthy families [0]. First off, this kind of compounding has only really been possible since the industrial revolution (~200 years). Before that, wealth came primarily from land ownership, which was zero-sum. Second, "no major bad luck" has been pretty hard to come by in most of the world across multi-generational time-scales. The US has had a historically exceptional period for the last 80 years or so, but there is no reason that has to continue. Third, "as long as descendants don't make errors" can also be a significant hurdle. Many Asian countries have a saying: wealth does not last past three generations (not meant to be taken literally, but people say it for a reason).

Also, to start compounding, you have to have enough to compound. Most people instead start off significantly in debt (student debt, mortgage/rent, etc.). Then they try to save enough to be able to raise their children and retire before they become too infirm to work, at which point they start compounding in reverse. All the while, they are competing with everyone else trying to do the same thing for how much they are willing to pay for scarce resources and how little they are willing to receive for their employment. Having your compounding achieve escape velocity is the exception, not the rule, and it has to be that way.

derf_··on Baumol's Cost Disease
Exactly. Even though Baumol himself used the phrase "Cost Disease", I think that framing distracts from the fact that it is a result of something desirable happening, namely increased efficiency in some sectors. You could also posit a case where some sectors become less efficient, due to badly conceived regulations, exhaustion of non-renewable resources, an unchecked monopoly, or some other factor, but you don't need a special mechanism to explain why prices rise in such a scenario.

> ...consider a case where finance becomes much more productive... leading to fewer people becoming doctors because finance is much more attractive.

This is the opposite of what one would expect from a sector whose efficiency increases, as modeled by Baumol. See the first bullet in the article: "The share of total employment in sectors with high productivity growth decreases, while that of low productivity sectors increases" (also see the detailed analysis in the Technical Description section). It might be theoretically possible that induced demand could still increase overall employment in a sector as its efficiency increases, but I think you have to make an argument why that would be true. During the industrial revolution, automation eliminated 98% of the labor required to produce a yard of cotton cloth, but between 1830 and 1900 the number of weavers in the US increased by a factor of 4, because demand increased due to lower prices [0]... although the US population also increased by a factor of 6, so as a percentage of the workforce weavers still declined, even as people consumed much more cloth per capita.

derf_··on Baumol's Cost Disease
The submission is titled with "Cost Disease", though the Wikipedia article has the more neutral term "Effect". But it is important to remember that money is a relative resource, not a real resource. If some sectors of the economy become drastically more efficient, and some do not, overall society has become wealthier, even if the prices in the latter sectors rise a lot.
derf_··on South Korea – A cautionary tale for the rest of humanity
South Korea went through an astounding period of economic growth. In 1961 its per-capita income was US$93 (inflation-adjusted). Ghana, one of the poorest nations in Africa, had more than double that (US$190). In 2024, Korea's had grown to US$36,624. That is almost 40,000% growth in a single lifetime. It is hard to conceive of in most places where GDP growth averages 1...2% per year. The difference between working hard to get ahead and trying to sit out and keep doing what you were always doing was literally the choice between affluence and destitution. So no wonder you have a population hyper-focused on their careers who pushes what children they have as hard as they can, so that none of them have any time for family now. The opportunity cost of anything else was enormous.

The positive news (if it can be called that), is that this level of growth cannot continue, so something will have to change.

derf_··on Berkshire Hathaway Announces Leadership Appointments [pdf]
Buffett has repeatedly said that Berkshire's size means it will no longer be able to deliver outsized outperformance. He also says that most people should invest in index funds. It is perfectly reasonable to just buy the S&P if that aligns with your financial goals.

> BRK-B's 5 year return is 2% per year more than SP500.

That said, 2% per year is generally considered a lot in diversified mutual fund / ETF land. You might not be able to charge hedge-fund level 2-and-20 fees for delivering that, but you could certainly charge multiples of what the low-cost indexers do (instead, Berkshire charges you approximately nothing). Now, Berkshire is a conglomerate, not a fund, and you could argue 2% is an appropriate risk premium for a single stock, even one as diverse as Berkshire (which is still less diverse than the S&P). But it is pretty impressive for something that is not a tech company. Those are the only things in the S&P that seem to be generating any returns these days (besides Berkshire, JP Morgan is the only other non-tech company with a market cap over $1tn, and arguably banks really are tech companies now, too).

> Apple is still 21% of BRK's publicly listed holdings

The public company investments are a minority of Berkshire's current value. The majority comes from wholly-owned operating companies and insurance businesses.

I don't want to discourage anyone from submitting patches, but that does not necessarily remove all (or even the bulk of) the work from the maintainers. As someone who has received numerous patches to multimedia libraries from security researchers, they still need review, they often have to be rewritten, and most importantly, the issue must be understood by someone with the appropriate domain knowledge and context to know if the patch merely papers over the symptoms or resolves the underlying issue, whether the solution breaks anything else, and whether or not there might be more, similar issues lurking. It is hard for someone not deeply involved in the project to do all of those things.

Have you never sat on public wifi and tried to open an http site? These days it is highly likely to be MITM'd by the wifi provider to inject ads (or worse). Even residential ISPs that one pays for cannot be trusted not to inject content, if given the opportunity, because they noticed that they are monopolies and most users cannot do anything about it.

derf_··on US car repossessions surge as more Americans default on auto loans
> "Distress in auto lending broadly is often seen as a bellwether to changing circumstances in the US economy, because Americans particularly in the lower-income brackets tend to put their highest priority in auto payments," said Brett House...

Or, put another way, when the bills come in, people make their car payments first, because they have to get to work. So either there are other bills people aren't paying, or people aren't going to work. Both seem bad. One purported cause of increased auto loan defaults is that people are having to make student loan payments again, although that would suggest they aren't prioritizing the auto payments.

derf_··on Beliefs that are true for regular software but false when applied to AI
There are four main levers for improving an ML system:

1. You can change the training data.

2. You can change the objective function.

3. You can change the network topology.

4. You can change various hyperparameters (learning rate, etc.).

From there, I think it is better to look at the process as one of scientific discovery rather than a software debugging task. You form hypotheses and you try to work out how test them by mutating things in one of the four categories above. The experiments are expensive and the results are noisy, since the training process is highly randomized. A lot of times the effect sizes are so small it is hard to tell if they are real. The universe of potential hypotheses is large, and if you test a lot of them, you have to correct for the chance that some will look significant just by luck. But if you can add up enough small, incremental improvements, they can produce a total effect that is large.

The good news is that science has a pretty good track record of improving things over time. The bad news is that it can take a lot of time, and there is no guarantee of success in any one area.

derf_··on The paradoxical efficient market hypothesis (2024)
Anyone who has lived through a market correction (the tariff announcements in early April this year being a recent example, though there have been far worse) should be able to see that market prices do not always accurately reflect even the consensus view of value (which itself can be wrong). As people are forced to de-lever, everything goes down at once, often by very similar amounts, even though it cannot be possible that everything suddenly lost the same amount of value simultaneously.

To quote Richard Bookstaber, "The principal reason for intraday price movement is the demand for liquidity... the role of the market is to provide immediacy for liquidity demanders. ...market crises... are the times when liquidity and immediacy matter most. ...the defining characteristic is that time is more important than price. ...diversification strategies fail. Assets that are uncorrelated suddenly become highly correlated, and all positions go down together. The reason for the lack of diversification is that in a high-energy market, all assets in fact are the same.... What matters is who holds the assets." (from A Framework for Understanding Market Crises, 1999)

Was the market drop an accurate reflection of the value that would have been destroyed by those tariffs, discounted by the probability that they would have been enacted as drafted? Nobody knew then, and I maintain that nobody even knows now. That was not the calculation that was being made.

Even in a language that is not "good" by your definition... you have basically just described a function. A wrapper function around a sub-function that has early returns does everything you want. I use this pattern in C all of the time.

derf_··on CEO pay and stock buybacks have soared at the largest low-wage corporations
> Why don't the sellers of the shares owe tax?

They do, but it is only paid by the people who took the money (instead of being forced to do so), and, more importantly, only on the difference from what they paid.

If you pay out $1mln of dividends, then everyone collectively owes (let's say at a qualified rate of 20%) a total of $200k. If you buy 20,000 shares from one guy at $50/share, you returned the same $1mln of cash to shareholders, but if he bought last year for $45, he only owes (let's say at a long-term capital gains rate of 20%) a total of $20k in taxes.
