Well it's odd that the government doesn't increase a 50% income tax band for high-earners because, for once, it seems to be a populist policy (something like 60% of people want to "hammer the rich")
But that defeats the entire purpose of being rich!
You are not supposed to be looted by the poor and the middle-class. That's just reeks too much class warfare, and besides, the rich people would come up with a brilliant plan: "Place their money somewhere else!"
Darth Insidious: Think of it this way. Scotland is not declaring indepedence from England. England is declaring indepedence from Scotland, after all, King James I was originally the King of Scotland before he took over the Kingdom of England.
