@LadyHarmby it was a political move. 'The bankers' were seen as the ones who directly caused the 2008 crash. Which they did, but only within a deregulated political and economic framework which let them, ie they were given too much power. So when they chose to do the wrong thing in pursuit of profit, they could - and then they could be financially rewarded for it.
The solution was to reform the global banking industry, but no single govt has the appetite to take that on. So instead, they limited the bonuses individual bankers could make which scored them a few easy political points - after all, we were all in this mess because of them in the first place, right?
In reality it has just meant that banks, not bankers, make and keep the profit.
The most 'talented' seek to work for global banks where they can earn unlimited bonuses. And the world keeps turning in much the same way it did in 2008.
Basically, it's easier to believe the whole 2008 crash was caused by that convenient bogey-man Fred Goodwin, and hit any future Freds in the pocket, than it is to reform capitalism.
