Banks are not that cause distrust. They are more angered by the fact that we do not understand anything, what happens to our money.
I like banks, because in a bank is a place where money is collected. So if I have a lot of money, the bank is a safe place for me to keep it. Conversely, if I go bankrupt because I am trapped in a debt from a bank and I am wrong to invest, the bank is not the place I like. The bank is a capital provider through loans so that customers can grow and progress so that they can have what they want.
