Well, we still 'lose' insofar as we're being paid less than bankers, yes. But the whole point is to mitigate 'casino banking' behaviour. The bigger you make the banker's performance bonuses, the more risks they're going to take. The more risks they take, the more likely they're going to stuff it up, crash the economy and look like morons.
I have no objection whatsoever to bankers being paid big money, I couldn't give a toss. What I do give a toss about is them using my and everyone else's money to gamble in the hope of getting massive bonuses, especially when the consequences of failure to them personally are effectively nil. I don't want them to able to make one single solitary penny by putting other people's livelihoods and pensions at unnecessary risk.
If the new laws make that situation one tiny bit less likely to happen, I'm all for them. And if it makes the daft sods bitch and moan, all the better.
