Xenia, I think the tax thing is a bit of a red herring - you're paid more because, as you've said, the market, for whatever reason, thinks that what you do is valuable. Within that valuable profession, you work hard and do well. All fine and good. But there will be professions which require as much skill, training and hard work as yours and which the market, again for whatever reason, doesn't value as much. So you make a good financial choice - you like a job which the market likes. That makes you lucky, and the tax bit could be said to just balance out that luck a bit!
It's a bit like comparing a professional footballer and an international-level swimmer - no distinction in terms of talent, dedication, amount of training, etc, but the market prefers football, so the footballer gets paid, and taxed, more. I can't bring myself to weep for the extra tax paid, tbh.
