This is my opinion.Banks won't make you rich.saving in bank can never do that,because of interest rate that bank gives you is too tiny.You saving will be simply be eaten up by the sleepy monster called inflation. As a example I will take ,When I'm in grade school,each day I received 10Rs (my country currency) from my mother.It was enough to by me 2 meals,but in now 10Rs enough to buy 2 candies. 
Banks are just for keep your money safe! 
Banks are just for keep your money safe! I think The bank is the safest place to save money, so safe the money you keep on eating every month by the interest rate applied by the bank until maybe the money you save will not be left as it continues to be undermined to pay the interest rate. Do you still want to keep fiat currency there? I personally have left the system they have been offering for a long time.
