No, but considering there is a huge difference between those earning billions and those earning £150,000, we should have tax rates closer to 100% for those who have already amassed huge wealth. We need to stop pretending that there is no cost to society for accumulation of wealth in a few individuals and tax it as such. Those earning £150,000 should have higher taxes than those on lower income certainly but the millionaires and billionaires should be treated differently again as they are the ones doing the most harm as they cannot invest the same proportion of their wealth back into the economy the way numerous top tax rate earners with substantially lower incomes would.
