The rich already pay more in actual amounts. If a person earns £5000 a year, a 10% tax rate takes £500 from them. If they earn £50,000 a year, a 10% tax rate takes £5000 (the entire amount of the first person).
If you earn 10 times more, you pay 10 times more. "Progressive" tax rates only punish the rich until the point where nobody is classed as "rich" anymore, and then because of the same progressive tax, the government gets hardly any money at all.
