Because the market has seen the state step in when the worst happens, it will again let financiers take on too much risk. Because taxpayers will be subsidising banks' funding costs, they will also be subsidising the dividends of their shareholders and the bonuses of their staff.

It should be obvious by now that in banking and finance the twin evils of excessive risk and excessive reward can poison capitalism and ravage the economy. Yet the price of saving finance has been to create a system that is more vulnerable and more dangerous than ever before.
Limiting banks' size could stop them from attaining the scale and scope to finance global business. Confronted with restrictions, financiers innovate - in recent years, for instance, risk was shifted to non-banks such as money-market funds, which then needed rescuing. Regulators can stop innovation, some of which has indeed been abused, but Luddites in finance would do as much harm to the economy as Luddites in anything else.
As the crisis has brutally shown, regulators are fallible. In time, financiers tend to gain the advantage over their overseers. They are better paid, better qualified and more influential than the regulators. Legislators are easily seduced by booms and lobbies. Voters are ignorant of and bored by regulation. The more a financial system depends on the wisdom of regulators, the more likely it is to fail catastrophically.
