In case anyone foreign is wondering, Rachel Reeves is in between appeasing her banker friends in London and anybody else who earns a significant income and there is a loud enough voter base in Labour who are ardent anti-capitalists that hate the private sector.
The anti-capitalists, usually comprised of hardcore socialists and communists, Have whipped themselves into an absolute frenzy in the past few years and are convinced that if the UK is so rich they can afford the high taxation.
This is why they have gone after farmers who they think are just using land ownership to dodge inheritance tax among other things, yes, they actually believe this. They can't do basic maths and think that there are bunch of rich people in this country hiding their wealth under the floorboards and in offshore bank accounts.
They don't understand that anybody who is even capable of earning an income nevermind already has wealth has up and left the country, this is it. If she increases taxes this country is done, so I think what she's probably going to do is go after the pensions instead but then that will of course piss off all the boomers who still think state pensions are a thing.
Labour vote share will continue to tank as a result, likely this will give rise to Corbyn's allegedly soon to be established left wing party, greens will also take votes. Keir Starmer refusing to back statehood for Palestine as France has done will indicate to leftists he won't virtue signal for them so they'll go somewhere else.
TLDR: We're just about at the breaking point financially for the UK, expect a market crash.
