I posit that even being in the top 10% is probably fine. The problem is a global economic system that isn't growing with the population and funneling the money to the 1%, as opposed to the 10% (which now just get by), much less 50 or 100% of the humans on the planet.
THAT is the real question. And, frankly, for the vast majority of Americans... an honest answer to that question sucks to think about.
