Banking is an industry that seemingly only grows these days, and banks cannot go out of business. Due to the systemic risks involved in running a bank, any failure of a bank can be viewed as a liquidity problem and will very likely get the support of the central bank. No other ostensibly private industry enjoys such an exorbitant privilege, combining the highest rates of profitability in the private sector with the protection of the public sector. This combination has made bankers’ work as creative and productive as that of public sector employees, but more rewarding than most other jobs.
