This is closer to what I was getting at. Above someone mentioned government assistance programs, which is also true to a point but not really what I meant (another 'disagree connotatively').
I was mostly going for the fact that circumstances of birth (family and status not genetics), location, and locked-in life history have far more to do with income than a lot of other factors. And those who make it REALLY big are almost without exception extremely lucky rather than extremely good.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
