Maybe if you spent less time asking false, unsubstantiated questions and spent more time working and improving your lot, you would understand more. Do you think Gates, Bezos, Zuckerberg, Buffett and more than I can count started out as millionaires? Nope. They persevered and worked hard to get to where they are. Don't covet someone else's fortunes--make your own.
I commend Bezos, Gates, et al, for starting small and building something big. No one hates productive people who contribute to society. The problem begins when they acquire the kind of wealth common to small nations and start abusing their power.
But the problem is, the internet allows for the cornering the market if you get in and move quickly into a new area. once these guys got a monopoly, or something very close to it, they started abusing their power, and that's where they violate antitrust laws, and should be held accountable. It's easy for these guys, given the laws, to avoid paying taxes, and on that point, I agree the OP. The OP isn't articulated very well, which could have been written better, and substantiation would be very easy. All of these guys have been subject to congressional scrutiny, etc., etc., etc., regarding these issues.
The fact of the matter is that the upper 50% own 97% of the nation's wealth (proof provided on request, the Fed Reserve wealth distribution tables) and given that fact, they should pay, a progressive tax that rises to 97% of the nation's tax burden. Currently, they pay less than that. The lower 50% own 3% of the nation's wealth but pay more than that percentage in taxes. For poor whom many claim to not pay taxes, not true. For those who cannot hedge, the poor, they pay it in inflation. Inflation is a transfer of wealth from those who cannot hedge (the poor) to those who can hedge (the rich). If you don't grasp this, I will detail it more, but it's a fact. Wealth isn't created out of thin air, though it might seem like it, someone pays the piper somewhere, at some point. The ultimate source of wealth is labor. And the less you work for it, the more others do, for you. If you inherit wealth, that means many others donated their labor for your benefit. That's what it actually means, and if economists started treating money as labor, instead of some bullshit abstraction, we'd come up with better monetary policy.
