I agree with that. I do think those limits just makes it a more obvious argument, but I thought the discussion was more general than an obvious subset of people who can have their pick of opportunities.

Even "lesser" schools without top tier academic stars are having trouble retaining and attracting enough talent to accommodate the current demand, and this is even with salaries starting in the six figures. Which implies the market for people with graduate level degrees possibly has a higher demand, and should translate into a higher salary.
