If I had the chance to earn it, I don't think I'd begrudge paying more tax on it.
"Oh dear, my gross income has gone down from £14,000 per month to £12,000 per month. How am I ever going to scrape by?"
1% of people are going to be affected by this and they are not going to be deprived by the effects.
And yes I do think if people earn that much money, they should be spending it on something other than themselves. If they're not, they're just very strange. Very rich people always spend loads of money on charity, good causes etc. Very few are famous misers. In fact, I can't think of any.
