I'm not going to argue against these guys success' nor will I say there have been "bad" for America. But if we take Bezos as just one example of what they were "given": Don't you think NOT having to pay State and Local Taxes for years was a massive gift; key driver of their success; and killed off many local businesses in the process - further creating their stranglehold on US Retail? Hell NYC was giving them $3 Billion to relocate. Amazon/Bezos have been given a lot.
At some point a person just can't spend the accumulated wealth. What's that number? I don't know but it's some $X Billion for sure. In addition, I feel like I could make a pretty good argument that if wealth were more equally distributed, Bezos specifically would benefit. In fact, dare I say, if wealth were more equally distributed, Bezos would become richer than the world's richest man.
Further - to go off on a tangent - I don't get why some of these guys just don't go out and do crazy good for society...merely because they can. If I'm Bezos, Flint Michigan would no longer have a water crisis. I've never even been to Michigan, and I would do that because doing so would be ####### awesome. No need for a tax write off, no need for a non-profit to pass through. I'd just write a check.
If you have the good fortune to start a business, and using the talent, resources and economic engine of the US to make $X billions for yourself. I believe at some point you need to "sacrifice" it back - you know to really Make America Great Again. There are people who were "given" far less but sacrificed much more (like their lives) so the the Bezos, Zuck, Gates, Buffett, Dell's of this country could build their companies and personal wealth. Why is it so wrong for the good of everyone, to ask them to "sacrifice" some of that back, still allowing them enough that they can never spend it all in their or their children's lifetimes?
