You missed the point. I'm saying rentiers bid up pricing in those professions, affecting them indirectly. In the US, for example, there's a very clear bimodal distribution in legal income between graduating lawyers who go to work for large firms and who mostly do corporate law, and the others who don't. The former pays more than triple the latter, so guess where most of the talent goes.
