I looked in to moving to Sweden. I had thought the tax implications would be utterly horrific but, really, it wasn’t that terrible. And once I’d looked at things in the round - particularly the difference in the costs of childcare.
I actually think that for anyone towards the higher earning end of things (I’m nowhere near troubling the 6 figure salary mark, but still in the higher tax rate) the UK is a shit deal. You do end up paying a lot of tax but in return you get pretty crap public services. It’s not like the system is doing a good job of redistributing things either. It’s not like you can even say that at least it went to ensuring children were kept warm in the winter, regardless of their parents’ income (or something else that might feel like the tax was worth it).
The UK has a pretty dismal offer for people who can earn pretty well but aren’t super rich and, therefore, don’t give a fuck what the state offers.
