In pretty much every western European country your tax rates can easily hit 60%+ (like the 100k 60% cliff in the UK). The budgets of these governments are all largely funded on the backs of middle class income tax - 40% of all receipts in the UK, plus another 10-15% from VAT - compared to a lowly 9% from corporation tax [1]. You have to wonder how the economy can ever evolve given everything is geared towards suppressing middle class earners from ever having significant capital.
