Idk if the lifestyle is really that special. I think US income is just heavily weighted towards the bottom. Middle class is disappearing as wages stay low for most people. Tech isn't rich, just comparatively. Tech salaries are what almost Americans should be paid.
Yeap. Since the 1970's and Reaganomics, the middle-class was continuously decimated to almost nothing.
In the US: you're either in tech or banking/finance, or you're shoveling coal to earn your cockroach protein block. From where I sit from yet another overpriced goddamn gentrification ivory "mixed-use development" tower of yuppies, I can see 50 tents of homeless people. This wasn't the case in the '80's.
