I don't get it, it makes no sense. The top rate of income tax that you would pay in those countries are 10%, 10%, 20% and 5% respectively.
We even have empirical evidence that by lowering your top rate of income tax, you get economic growth and investment.

If I was a rich person here I'd be gone in a flash, having to pay 50% tax, next year it'll be 45% but still, it dwarfs what I'd have to pay there. Why is there not an exodus? People could just leave here and go over there and take up the job they had here. This is why we need to be very careful about penalising and stigmatising the bankers. British financial services helped make this country great. If we're too tough on them, they'll just leave and go to one of those countries. Any tougher and we'll have a mass exodus.
The job creators too, Simon Cowell, Bob Diamond, Alan Sugar, James dyson etc. there comes a point when you just get in the huff if people are taxing you too much and think what's the point and leave. These people could all be going if we don't lower taxes. Why else do they work? If the government is taking more than half what you earn, there is no incentive to work. These people will just stop working and leave if we're not careful.
