Nursing comes to mind. I generally think of it as a high-stress but also pretty highly-paid profession in the US (can do 100k+). In Europe pay is shockingly, appallingly, pathetically low (true of tech as well, but you can get out of that if you push hard enough, and I find the work culture superior).

I mean, I left the US, but my general experience has been that if you work in the dregs (and I've been there) you're better off in Europe, but if you work in a somewhat well-paid field, you'll make more in the US (whether you're "better off" is a more complicated question).

Not sure what opportunities there are for a former MP like yourself though.
