Leaving aside Wall-street the Tech Bubble where people work grueling hours in the hopes of becoming a millionaire, the rest of the US works grueling hours because they need to in order to eat, pay their rent, etc. Telling someone who is working 40+ hours in order to make ends meet that they need to "work less" is tantamount to telling them to become homeless and destitute.
The point to a more progressive tax system. If the goal is to maximize a number(GPD) then a less progressive tax system makes sense. If the goal is to maximize "total human happiness"(could use a better term here I know) you need a more progressive tax system.
That is not true. Some tech people go in hoping to be millionaires, but the environment is extremely cut throat, esp with competition like India with billions of people keen on dominating tech, as well as Chinese skill. Many of the tech people end up competing to stay afloat, and to eat the weakest dog in the pack just to stay in that arena.
Silicon Valley and Seattle/Redmond are probably the most cut throat areas you could work in. It gets really nasty there.
