No I don't (disclaimer, I am NOT a banker)
Banks were bailed out (including Northern Rock which had no 'casino' department other than lending too much money to people who could not afford it) because without a stabel banking system ALL sectors and industries go into free fall.
If you cannot deposit money safely, you have no economy. Everyone would have suffered ethe fall out - nurses, small businesses, builders, EVERYONE!
The media and large swathes of society have very little understanding of what banks do, who 'bankers' are and what caused the cirsi. It was not jsut the bankers. The government and many other sectors were complicit and gained and encouraged from cheap credit. As did many individuals.
It is convenient and politically expedient to have a nice little group to scapegoat for the crisis.
If you expect bankers to give back their bonuses what about lawyers, management consultants, footballers, small entrepeneurs etc? Why just the bankers? Why not have everyone earn the same amount and everything else goes back to society, oh wait sorry that is communism and it does not work.
If you make UK uncompeitive place for financial services itts not just greedy bankers (who you may say good riddance to) that you are puttin goff doing busienss here. Its the 1000s of related businesses and counterparties. You are also going to lose a huge chunk of tax revenue.
I think so much chat about bankers bonus is simplistic in the extreme.
