We've also seen a huge compression in net income as the tax thresholds haven't kept up with inflation. So someone who paid a 20% marginal rate twenty years ago is now paying 40% on the same real-terms income. And the 0% personal allowance has been eroded too.
Not to mention the 60% effective marginal rate between £100k and £125k - 69% if you have student debt, oh and that's not even counting employee's NICs.
And don't get me started on the stealth tax that is employer's NICs. (Those were just increased even further, and the morons are all defending it by pretending it doesn't come from wages... where exactly do they think the employer gets the money from?)
Plus all the insane traps where earning extra money can actually reduce your net income. E.g. there are situations in which increasing your salary by £1 can leave you thousands of pounds poorer because certain benefits are withdrawn with a cliff.
What's the point in working harder? You'd think that with such eye-wateringly high levels of taxation, we'd at least have something to show for it in the public sector, but... okay, I need to stop writing now for the sake of my blood pressure.
Everyone goes on about the 100k issue. For 10 years I paid 60% between 50 and 60k due to child tax. The child tax has recently shifted to between 60k and 80k and reduced so it’s now about 51% (plus student loans)
