It's not about not liking the UK, or even liking it. It's about the political and financial system that spoils the place, just like it spoils every other Capitalist nation. All of the organisations and institutions you mention (and a lot more besides) are expressly designed to nurture and support the destructive and counterproductive, corrupt and incompetent Capitalist system status quo in the UK and, as such, must be removed - which also applies to all the other Capitalist nations. Wherever you go in the world, you'll find the same; a selfish, entitled, corrupt and malevolent privileged class solely intent on preserving its wealth and privileges and not caring what happens to the rest of the population.
But my point still stands and you still havent answered the question I asked which was Why Not move to a (Socialist) country that doesn't behave like this
One of the Scandinavian countries perhaps or North Korea*
