Surely the thing to focus on is the fact that the new 50p tax rate will probably raise almost no money?
I only did AS-level economics, so am not an expert at all. However, I am highly sceptical that the 50p tax rate will work. In the 1980s the top tax rate was cut from 60% to 40%, and tax revenues actually went up.
People who are professional economists (independent of any political party) have studied this question:

Ignore all the gobbledegook, and go to page 26 for the conclusions - basically, they say that the new top rate will probably actually lose money overall for the exchequer (but not much).
I don't know whether to believe them - to be honest, I think economics is bit of a voodoo science. I believe them a lot more than I believe Gordon Brown though, who has been consistently wrong.
If the new tax will raise no money, then you have to ask yourself what the point of it is. The answer is that Gordon Brown wants a political dividing line to distract attention from the fact that he has screwed up so badly.
I voted Labour in 1997 and 2001, and Tory in 2005 - but I would never vote for the "old Labour" policies which Gordon Brown is bringing back. It was very easy to vote for Tony Blair, who made aspiration OK again for the Labour party.
That said, bankers really shouldn't complain too loudly. They would be out of work if not for taxpayer money.
At the end of the day, though, I think unless people are BNP, there is no point in getting angry about their politics. Unless, of course, they are politicians, in which case, they are fair game!
Is your friend kind and funny? If so, why care whether he begrudges his tax or not?
YABU.
