This is blatantly false. Income tax on higher earners in the UK has decreased since the 1970s/1980s when IIRC the highest tax bands were over 70%, if not higher.
Your article doesn't directly talk about the tax rate for the top 1%.
The fact that the percentage of total tax collected attributed to the top 1% has risen from 24% to 30% seems to be more indicative of higher wealth inequality, especially if the figures the other posters have mentioned about lower total tax rates on the rich are true. To me that's a good reason to raise taxes on top earners and lower taxes on the middle class.
When you make most of the money, you pay most of the taxes. You can't squeeze blood from a stone. 10% of a billion dollars is a lot more money than 50% of $100,000.
Have they fallen generally, or has the highest tax band fallen?
Germany had the highest tax rate > 50%, it's now 42/45%. At the same time, the income required to be taxed at that rate hasn't changed with inflation, so while it was e.g. 52.152€ in 2002, it's 57.051€ now - adjusted for inflation, it would have to be closer to 75k€.
Lowering the top marginal tax while not adjusting for inflation so more people get pushed into higher tax brackets from below is great if you're rich, but shit if you're not.
