The UK has a long history of gouging rock stars for taxes. Take the case of the Rolling Stones, who moved to France in order to escape an 83% tax rate. The result was Exile on Mainstreet.
Bowie moved to Switzerland for much the same reason. Members of Pink Floyd all left the UK for a year to avoid getting soaked.
Bad Company, Rod Stewart, even Cat Stevens bailed on the UK rather than give more than 80% of their income to the government.
More recently, U2 moved their business dealings out of Ireland to the much more tax-friendly confines of the Netherlands.
So what's the point of this? Only that "tax the rich fuckers" sounds like a good government policy until you are the rich person being taxed. Not only that, it illustrates how easily rich people can avoid these kinds of taxes simply by moving away. Having a house in a Bahamas is certainly not a burden, particularly when it "pays for itself" in tax savings.
It also illustrates how we are all hypocrites in this regard, particularly people who profess "liberal" views.
The sad part is, these multi-millionaires can afford the accountants and lawyers who can lower their tax bills. They can also afford the villa in the South of France of the house on the beach in the Bahamas.
The middle class and the upper middle class - stuck with the tax bills after the very rich have fled - cannot afford these sort of dodges.
They just have to pay.
