Care to elaborate on why this is a bad thing? Also, software salaries are not all salaries and are probably not all that representative to the bigger picture.
Some employees that capture a piece of that wealth funnel it back into more startups/growth (Silicon Valley) creating more jobs, more growth and more wealth (not to mention whatever the new startup is doing is usually creating a new thing people want too).
Software salaries are extremely high, but software companies in the US pay a lot in non software roles too.
On net you end up way in a way richer society that operates this way vs. one that incentivizes not operating this way.
That doesn't mean there should be zero protections from abuse, but it's important to be cautious about the net effect of these sorts of regulations and how you can end up trapped in a worse local maximum because of them.
In a society where you can take bigger risks, make bigger bets, you can get a lot bigger wins at scale. I think that's a good/important thing.
