I don't understand your last sentence. You can do the math if you care to but if Bezos gave away 90 % of his yearly profit how much would each poor person get?
And how do you decide which poor people are poor because they have no ambition? And what incentive would poor people have to help themselves if they can do nothing and wait for their yearly stipend from Bezos?
If he paid living wages, his workers would live better and create more demand for goods.
Same for Walmart.
Same for Target.
Etc...
Increasing demand creates new jobs, not decrease them.
Billionaires consolidating money and effectively removing it from the economy doesn't create jobs.
