Banks do not store their deposits in a cash vault. They loan it out (except for a reserve percentage), and charge interest on the loan. That's how they make money. That's why they offer free checking - so they can loan your money out and charge interest. They will even pay you to deposit your money, so they can loan it out and make money on it.
Wealthy people know how to make money, which means putting the money to productive use creating goods and services that people want. If that money is confiscated from them, there's that much less money creating goods and services people want.
