It's pretty absurd of him to talk about how it's ridiculous that people are paid $50mil (I agree) then pivot and say that $120,000 per annum for a new grad is another example of "ridiculous comp." These things are not in the same ballpark, they are qualitatively different. I don't know the author but this is so bizarre it makes me question their analysis overall.
The reference was to new law grads 20 years ago getting $120k jobs. That indeed was a high starting point for most recent grads from most fields 20 years ago.
