That is "literally not how it works", as you missed "... and losses".
Since dividends aren't really a thing any more and gains are ~100% from stock prices increasing, existing holders of securities would really like a bunch more money to come shopping and drive that price up. Very helpful if you want to make sure a period where "... and losses" seems like a silly thing to be worried about keeps going for a while longer.
Bunch of folks out there would love to be taking management fees on funds that're required by law to receive 10ish% of every middle-class-and-under working American's paycheck (some at the higher end of the pay scale pay less than that, because of the cutoff, and of course anyone rich enough not to have wage income pays no FICA at all).
Others would like to game the system to make Social Security a huge, deep-pocketed buyer for their scams. This is for when "... and losses" starts really biting people.
