You shouldn't, and that isn't my argument. If Gravity was paying some people $40k and some people $75k for the same work and result, they were being economically irrational. I'm saying that the $75k worker, up until today, was someone who likely commanded $75k because a) their training and experience allowed them to do productive work that exceeds that of entry-level workers, and b) they are harder to replace than entry-level workers.

If your employer says "your value to this company is equivalent to the value of unskilled entry-level workers", when you are in fact a highly trained and experienced worker, that may well be difficult to swallow.
