That's a pretty broad statement to make, especially with the implication that the only way you can become rich is by basically committing borderline fraud.
If you want to get rich, spend less, save and invest more. Nothing about that is fraudulent, and many would argue you'd have a more fulfilling life in the process.
Spending less and investing isn't going to make you rich. It can certainly help, but it's definitely not going to get you rich unless you have a large amount to begin with in saving and investing.
Secondly, any of the "holier-than-thou" wealthy people that primarily just have good jobs seem to overlook the fact that they are enabled by an entire cadre of people stepping on others and committing those grey area border-line frauds. Much like how we overlook the sordid conditions in foreign countries to enjoy cheap (or expensive) products. It's extremely unlikely that there exists a major corporation that isn't exploiting loopholes, maintaining a legal team to skirt regulations, and engaging in practices that are legal but ultimately not beneficial to their customers.
It's not wrong to make a profit, but there's a level that's fair and reasonable and in many cases the profit margin is correlated to the morality of the provider. The willingness to harm others for profit is a necessary component to become rich in all but a very few edge cases.
Price is what you pay, value is what you get. If a contractor has a brand new truck, never hire them. Without fail the best work I have had done was by the businesses with the worst presentation. The shoddiest, felt like a scam, was always by the flashiest companies.
Advertising at its core is a way to create a falsely inflated sense of value to justify a higher price. The primary way to get rich is to prioritize profit over providing a fair value.
Even Doctors are provided with their high salaries only by an artificial limitation of supply and a variety of opaque exploitative practices.
So the first step was to see if there's any unethical ways at all.
We'd have other steps after that.
It's always possible to dig deep enough and find questionable moral things, in this case, it would be about the platform, how customers are reached etc.
But that's far from my point, it's not reasonable to expect someone to avoid all creations derived through profits.
It's that the overwhelming majority, 99.99% of people who become rich are directly engaging in these questionable practices or are very directly supported by those who do.
Even making the video game likely makes you dependant on Microsoft, Apple or Google and the ills of their rise, but I see that as far enough removed that yes the solo developer could be considered reasonably ethical.
But again, how often does it happen?
In the US there are 1.4 million people with a net worth of over 10 million. How many of them were solo developers with a non-exploitive products that didn't sell out to someone who made the product exploitive?
If by "rich" you mean "Elon Musk or Gates" then you may have a point.
The phrase 'normal decently paid' is doing a lot of work here. You absolutely will not 'get rich' on the median wage in almost any developed country, irrespective of your 'thrifty savings'. Given the rising cost of housing, and the increasing inaccessibility of home ownership, anything but an income well in excess of that accessible to a supermajority of people is unlikely to result in housing security, let alone wealth.
Without trying to antagonise, I do think this perspective arises from an ignorance of how much more hackernews tech people earn than is actually 'normal'. For example, here in Ireland the median wage is €45,537. In the US it's $63,795.
With luck, continual employment from graduation, no major health challenges or other unanticipated life events and marriage or long term partnership, it may be possible to one day own a home on these salaries. It's virtually impossible to be 'wealthy' or 'secure' in any usual sense of the word. Given the two recent recessions, and the changes in family composition very few people I know are in these circumstances. Most are renting in precarity.
There's no denying that more money helps, but looking at https://www.marketwatch.com/picks/heres-how-rich-you-need-to... shows it can be done at varying levels.
Again, if the median is $63k, that means half are below that; if you're at the median and you live below the median, you're saving money. 23% live below $35k, so if you make $63k and live like you make $35k, you should be able to save at least $10k a year or more.
Of course, choosing to spend your money on divorces and child support greatly hampers things (and those are choices, even if you feel it's the only reasonable one).
You're discounting tax. At least in Ireland, as a PAYE worker (employee) your take home would be 32,228. Given rent, food and bills, it is not remotely realistic to assume savings of that level. Still less save for a deposit or a house or apartment, climbing onto the property ladder. Can you live below your means, sure? Will this provide enough capital to meaningfully invest? On its own absolutely not.
It's much harder for me to guesstimate tax and expenses for the US, but I'd assume similar is true.
You're also assuming no children - which is a pretty grim, but realistic assessment given these income levels. At a median income level having children now actively puts you in poverty.
You start with the Earned Income Tax Credit - which basically takes your 0% federal rate and refunds even more to compensate and overtake social security tax.
Then you have ACA subsidies that eliminate healthcare costs (or greatly reduce it).
And then there's the Child Tax Credit - up to $2k per child. This one isn't refundable so you end up having some room.
All of this is just on the tax form - this does NOT count any of the other assistance available.
The surest way out of poverty in the USA - assuming someone is actively trying their best and not wasting anything, time, talent, treasure - is to be stably married and have some kids.
(All my comments are around the USA of course, I have no experience of Europe or Ireland in particular - but everyone online always assures me that Europe is a paradise compared to the complete hellscape that America is ;) - so I assume y'all doing pretty well. If not, come on over! We have some statue about it.)
Cursory search seems to indicate that ACA is still quite expensive for low earners - https://www.forbes.com/advisor/health-insurance/how-much-is-....
I really don't know what you're suggesting here... We're discussing the possibility of attaining wealth by saving / investing on a median income, and you simply haven't supported the assertion that that's possible or likely with anything you've posted.
Income inequality is larger, and social mobility lower in the US than at most points in history, and this is largely true for Europe too - https://en.wikipedia.org/wiki/Socioeconomic_mobility_in_the_....
As someone actually living on an income in this ball park, I can assure you that tax credits aren't money, they're just less tax debt. And that the concept of having kids on a low income would actually be terrifying.
But ... they are? Money is fungible; if you owe $1k in taxes and you get given $1k in cash, that's the same as if they just make your tax burden go away.
And it's clearly obvious that it can't cost $20k a year to raise a child, as many families are below that in income ("In 2022, there was a total of 7.4 million families living below the poverty line in the United States.") - if it costs $20k to raise a child, and there are 11.6 million kids in poverty in 2022, then the average poverty family has 1.5 kids, costing $30k a year - but the poverty line is between $23k-27k for a family of 3.5! So the kids cost more than total income, which is patently absurd.
Anyway, the whole point of it is - are you the lowest earner in the country? No? Then someone makes less than you and lives on it. If you mimic them, you will have something to save.
But people don't want to do that. They want to say "woe is me, everything is shit, might as well buy that burger" and continue as a debt-slave to the corporations.
As to the first, the benefits of children are somewhat financial, if you take advantage of them and you'll be too damn busy to spend any money on anything but. But the "stable marriage" part may be way more important.
Still... is it really rich? It's upper middle class. You want for nothing, financially. However, you're going to have to work about 50 times longer to start to get into the big boy's club. The gap between the middle class (even at the very upper end) and the truly rich, at this present time, is beyond human comprehension in that way. See you when you're 3000 years old. People who have that much money did not get there by working.
Most people consider rich to be about "twice what I earn/have" and it slides.
I think rich is much better looked at from the time perspective - if your time is yours and not unwillingly sold to others; you're rich. If your time is not your own and you have to sell most of it to live, you're not rich.
And yes, I would put anyone who can comfortably retire before social security kicks in (so, early retirement/FIRE) as at least rich-adjacent.
