I think it's part of the educational scheme to keep banks in power

ahh, interesting. It would seem that those banks have a lot of power. everyone works for a month for a paycheck, pays interest on their credit card if it's not paid off on the last day of the same cycle.
people there seem to know how to economize very well, and those savings gets placed in the bank which charges interest on balance.
and they materialize your property through re-lending (like they all do). Risk-free business
