If by "countries with higher paying tech sector" you mean the USA, with all due respect and without going into a huge discussion, I much prefer staying in UK, or the European continent in general. There is more to life, happiness, comfort, long-term goals and self-realisation than the number of dollars deposited in my bank account by my employer.
With remote working and the Internet the idea of relocating where your job is, is quite antiquated, at least for my standards. If I really need the money, I'll try and find a way to get paid US salaries while living in the EU.
As a software engineer working 100% remote and living in London I get paid 3-4x the average London salary, which is enough _for me_ to live more than comfortably and I don't really feel I need to earn $500k a year to improve my quality of life. I can't afford a private jet, but I don't need one, either.
