The study doesn't say it went into the 1%'s pockets. It says it went to 2 places:
1) The salaries of corporate employees 2) Shareholders and capital owners
Regarding number 2: "Shareholders" would include anyone who owns any stock at all, including a lot of middle class people with a simple S&P 500 ETF in their portfolio.
And the increase in productivity allowed more people to become capital owners, AKA entrepreneurs. The explosion in software entrepreneurs, for example.
Then why are wealth inequalities exploding? Why are we just about to witness the first trillionaire?
Because no matter what fairy tales you want to believe in your $20 "invested" in palantir won't make you a "shareholder" lmao
#2 only works if the public is allowed to invest when the new technology is in its early stages, which is currently not the case. Microsoft went public in 1986 at a valuation of $2.3 billion (in today's dollars). What's OpenAI / Anthropic going to be worth by the time they IPO? $1 trillion? $2 trillion?
