er money is not unlimited in the real world either!
Anyway, lets not talk about finance and interest rates and inflation and micro/macro economics now for a game.

There are diffrent interests depending on how long you will keep your money in a bank as well as for how much money you put in. Generally we make a pittance compared to what banks make out of the money we put there even for a day. The bank does not necessarily use my money on a daily basis but what they Can accomplish by having ready funds and being able to invest it to fund other project of theirs is how they make their money.
In any case, we are not disagreeing anywhere, I am just saying things with banks are not as simple. Also, working in a bank does not make you an expert

having a degree in Finance, a masters in Finance and... running a bank does. And even that is not enough some times
