Relative to other jobs, not in absolute terms (which isn't very meaningful to compare). Lots of specialized jobs start out well paid and then spread out over time as more enter the profession. Airline pilots, for example, used to be a lucrative job but isn't now. School teachers used to be paid well. Engineering is a bit of a mixed bag, but there are plenty of examples there too. Medical doctors is the common exception to this.
