Perhaps most billionaires did not come from other billionaires. But can we really act like tech billionaires didn't have enormous advantages?
Gates: Parents were quite well off and influential.
Bezos: Same, parents gave him hundreds of thousands to start.
Musk: Father owned an emerald mine.
I could go on, but I won't, because you get the idea. How many people in the wealthiest 1000 came from families in the bottom 50% of wealth/tax brackets? How many from broken homes?
And for the most important point, this doesn't even matter: the issue is that it is our financial and tax system, not talent or social contributions that allows billionaires to exist while others struggle. This system could just as easily say that nobody can control that much wealth and ensure a more just distribution, and many think it should. The whole article is a deflection and distraction from the point that a few people are unfairly awarded a disproportionate amount of resources.
