I actually agree with this, I used to work in sales myself and saw this happen. The bonuses drive the behaviour and that is invariably short term rewards. For example where I worked there were deals done that basically made the company no money but had large contract values so were chased down to completion by sales poeple in order to earn the bonus even though the company made nothing or even lost money on the deal.
In any case, I don't think there is really a case for regulating down to that level. The simplest solution is that when a bank or other business is inadequate in policing this stuff itself and then it fails. DONT THROW GOOD MONEY AFTER BAD AND LET IT FAIL.
What is our investment in HBOS and Lloyds worth at the moment..?
