Nothing wrong with taking some money from the very wealthy to redistribute amongst the poorer or better still to fund public projects. I know of a group of workers who earn anything from £25,000 to over £100,000 a week and earn more money than it is possible to spend. these same people can earn several hundred thousands or more for a few hours work endorsing a product. Very good at what they do some of them may be but lots of them are no better at their chosen profession than I am at mine, which happens to be nursing and I get in a year what the average erm, footballer gets in a week.
As for taxing the not quite super rich, yes flaws in the scheme but there is so much money sloshing around that hospitals and hospices shouldn't be having home made jam sales to survive.
Anyone that wants to leave britain so that they can keep their millions in the bank sitting there never being spent, well they can fuck off as far as I am concerned.
