Banks love money more than anything but you still need to follow some rules, but the rules don't come from the banks but from the governments, governments own the fiat and if you are going to do deals in fiat then you need to follow their rules is that simple.
The opposite I could say. That is, banks literally put the rules and of course banks have the money. Governments all over the world are groups of people with very good salaries and their main goals are to follow and implement faithfully what the bankers have already decide. On the other side banks always want to fund companies that in the future will succeed and they will have certain profit and possibly as someone above has post they can control through its loans.
