So where do you keep money if not in a bank account? if you put it under your mattress, and it is discovered, the assumption is that it was obtained illegally and it is confiscated.
If you keep it in a bank, the government sets interest rates at an effective negative rate and thus steals your money that way.
If you keep it in a retirement account, the fascist marxists plot ways to take it while making you think that they are helping you.
You keep it at the bank...in a safe deposit box.
