Bank on bankers?

To 'bank on' something means being able to expect or rely with confidence on it. Given that: bankers have lied to make them look more secure during the financial crisis and to make a profit (here); and have mis-sold specialist insurance to thousands of small businesses (here); on top of PPI insurance mis-selling, taking huge, fat, undeserved salaries and bonuses, and helping to take our economy and others to the brink...we clearly can't be confident that they operate within a decent ethical code. Our banking system's reputation, integrity and trustworthiness sinks even lower. Culture change is certainly needed if we are to build an economy capable of being sustainable (more here).
