Progressive tax on income is good, lowering taxes that disproportionately affect lower earners, like VAT is also good. £80k a year is a lot of money, even in somewhere really expensive to live you can cover all your basic costs of living and so afford to pay more tax, and that tax would only be on the money you earn over £80k anyway, so 40p, or an extra 20p if you're on £80001.
