I think you have to start moving out of PAYE and looking at 'wealth' to hit 'the rich' and to me I think we are talking about multimillionaires in wealth terms.
I mean 100k is nice, and far beyond anything like my earnings, but as you say its just an income that someone has earned by putting effort in, in the right field. Its already taxed more than fairly as we dont have flat tax.
Its very different from having lots and lots of shares or inheriting lots and lots of properties.
Absolutely. It's the higher earning PAYE employees who have been royally screwed ever since the financial crisis with ever increasing tax rates and carrying everyone else, while self employed people and business owners and people who are actually rich, and have wealth, contribute very little. You can't squeeze higher PAYE earners more, they have nothing left.
I dont know how we tax wealth not income without everyone just putting their wealth somwhere else though.
A good start would be a US-type approach: all UK citizens are made liable for UK taxes on their global income regardless of where it is earned, and all UK residents likewise, plus change the tax code to crack down on transfer pricing out profits earned here lower tax jurisdictions. And a big increase in capital gains tax.
Meanwhile though of course there also needs to be a proper industrial strategy, reversal of Brexit or as a minimum rejoin the SM and CU immediately, at least doubling of the funding for state education and adult education, energy, food and water security strategies, huge infrastructure investment, total overhaul of the dysfunctional health service model and state pensions and public sector pension funding. It would require capable politicians with foresight and vision and some conviction to do what is needed. So it won't happen.
