To play devil's advocate - since we're talking about "pay yourself less than Google" not "pay yourself nothing" - what would happen if someone was throwing tons of money around and telling founders (and early employees, while we're at it, who also take less than Google et al) to pay themselves several more hundreds of thousands of dollars a year?
They'd attract a lot of people to fund, for sure.
You'd lose a bit of a filter around risk tolerance to try to weed out scammers, though. There are absolutely a bunch of people who would take that money with no intent or ability to deliver a solid company in the end.
So they'd probably want to be EXTREMELY selective; moreso than Google by far since there the financial loss is smaller both absolutely ("one bad hire's salary for 6-12mo" vs "a multi-million dollar seed investment") and likely as a percentage of revenue/bank account.
I think they'd either get ripped off and disappear in a few years or just be small and stay small and not make a huge difference overall.
It doesn't seem entirely different than the attempted Softbank "de-risk startups by picking a winner early and pouring in crazy $$" approach.
