If you can’t figure out how to turn enough profit on your $10B company to pay the wealth tax, then you have to sell enough of it to pay the tax, and someone else gets more say in how the company runs.
What’s actually more likely to happen is executives would take a higher salary to pay the taxes and pay their employees less, because the last thing they want to do is be forced to sell shares which is the same as giving up ownership and control of their company at that level.
So yes there might be more taxes, but itd be at the disadvantage of the employees, and the government will give it all to DND anyway and you’ll never see a dime of it.
