Re: What a strange study
I am quite convinced we need banks, i.e. for handling payments and turning short term deposits into long term credits How would most people buy a house?
An example of a fixed amount of money is a gold-based currency, that has its own set of problems and does not eliminate interest.
Interest is the payment for deferring your consumption.
Another thing is the mixing of investment (Casino) and retail (utility) banking. I think it should be separated, as the Glass-Seagal act did (now unfortunately repealed).
