I can tell you that I’m a not terribly highly paid software dev (by US standards) in Ireland and my marginal tax rate is about 50%, and it could go up a few points if I made more. Add 40% tax on cap gains as well. And bank interest. (I get < 1 eur a year in interest, and they send 40% of it odd to revenue. Why bother? Hell if I know.)
