Beenbeta,
Basically, I agree with you, particularly about the last part. If they had allowed the banks to go bankrupt and then bought the assets out of bankruptcy, made good the savers etc, then they could have employed who they want and not been bound by the guaranteed bonuses.
On the other hand, if you remember the period, everyone was in full panic, and, had they done the "right" thing, even a couple of weeks delay in making the savers good could have caused a full scale run on the banks.
Having worked in investment banks for over 20 years, they certainly started being client focused. Over the years they lost their way, becoming more like tacky supermarkets, forever giving special offers on highly processed products which were very unhealthy for the consumers.
However, I still believe that, if the banks ever fully repay the government, cease to be dependent on special facilities and the "too big to fail" concept is somehow dealt with, they should be free to pay what they like. Why shareholders allow them to could be an interesting subject for a whole new thread!
