I just feel like no matter what any government does the ultra rich will find a way to get around it. Look at the US gulf south: they are in a race to the bottom when it comes to tax breaks and just giving everything away to businesses/high income earners, yet they are poorer than ever. Texas and Florida are the exceptions here to a certain degree but they are also massive states with lots already going for them. Their neighbors collect a fraction of the taxes they should and get nothing out of it except aggressive resource extraction and cancer.

Then look at the other end: are wealthy people and businesses really fleeing New York and California in droves like conservative media is portraying? Do we really see a meaningful wealth exodus occurring because of their corporate and personal tax laws? A cursory search says no. High housing costs, remote work, and just general pandemic shifts explain basically any changes there (and the number of people/businesses leaving isn’t particularly abnormal)

All of this is to say I don’t really know what the solution is for the UK. I just don’t think businesses and the super wealthy respond 1:1 to these policies in the way that politicians claim they do. They are so rich they are ultimately going to live where they want and do what they want. They aren’t going to relocate themselves due to tax policy. They will just “be rich” their way through the problem.
