Ruthless capitalism is the only reason people can even earn the ridiculously high Google wages in the first places.
Google can fire a small town's worth of employees and only lose 6% of their workforce. These companies are ridiculous in size. Really, this was only a matter of time.
I wouldn't like to live in the USA for the extremely weak employee protections there despite the massive amounts of money you can earn compared to Europe. Personally, I'm all for better employee protections to balance out the overpowering employer, but those protections don't come for free. If a company fulfils its social purpose of making people earn their living for a long time, they also need to be ready to pay their current rates (and up) for a long time. More protections means higher risks for companies, higher risks means fewer hires and lower rewards in case you can't get rid of someone in an economic downturn.
I think these protections are worth it, but I reckon the highest earning American programmers and managers wouldn't; the more you earn, the more those protections will cost you. Applying European protections wouldn't immediately drop wages down to European levels (you need a strong welfare state and such for that too) but it would certainly reduce the amount of disposable income these people have.
