The report suggested multiple policies to attain "wage equality", including increased taxation and forcing companies to increase pay for subcontractors. The result of such policies would be downwards redistribution: less pay for high-skilled workers, more pay for low-skilled workers.
I'm sure you don't think that "wage equality" means that janitors in SV start making $250+ like senior engineers. That is not sustainable. Any realistic solution would bring engineers way down, while lifting the bottom a little bit higher.
I'm not sure when "equitable pay" became a goal. In a healthy free market, people are rewarded for their effort in developing rare and valuable skills. As far as I know, a market in which the government actively intervenes to keep all wages equal is called communism.
If the government wants to take action, perhaps they should work to make SV more affordable for everyone, for example, by lifting ridiculous NIMBY restrictions that keep housing expensive.
All those "high paid engineers" still can't afford a home anywhere near SF. Somehow I doubt the solution is to cut further into their pay.
