I'll take the other side of that argument. It's an interesting article! But it doesn't make me think that the numbers are "rigged," just that they have been misinterpreted. Semiconductors are getting way better, and have been for a few decades, and that counts as an awesome productivity improvement in manufacturing. If you just look at the top-line number, it says "manufacturing is getting more productive," which in an aggregate sense is still true! But it seems a lot of people though that meant "manufacturing is getting more productive because we have a lot of robots" even though manufacturing employment is declining, rather than "manufacturing is getting more productive because our semiconductor fabs are awesome and the rest of the sector is bleeding out." Which is what it actually meant.

The "US manufacturing is super productive" narrative is unfortunate, especially if policymakers were making decisions based on it. But it doesn't really call into question the data or methodology, just that people have misinterpreted it. But the people who are actual experts in this area are writing papers about that! This paper is from 2014[1], and she's been writing about this since 2010! With economists from the Federal Reserve system, no less.

edit: I guess my point is, the point that article makes isn't, "the game is rigged, inflation is made up, we should use shells for currency." The point it makes is, "don't just read the top-line number and then write an opinion article, make sure you read the breakdown first."

Also, assets do hedge inflation. Most of them, anyway. I never argued otherwise. Just that asset price increases are not the same thing as inflation.
