Why do Keynesians operate under the assumption that people are stupid?
Look.
If I know that next Thursday the government is going to confiscate 10% of my saving’s deposit, I’m going to start taking as much money I can out of the bank.
And the economist are always shocked that people behave this way.
A question for you.
How do you know that the bank will not take 10% out of your account next Thursday?
