But consider this:
Paul Allen is awesome at business, so we want him to work for as long as possible.
But if his dream is, say, 5 yachts, then he can quit as soon as he has the money to buy them.
So in order to make the most of his talent, we should tax him heavily, thereby delaying the moment when he has saved enough money to sail into the sunset in style.
Because leftists live in fantasy land and ol Paul is going to let you have your way with him?
