The introduction of the “equal pay for equal work” argument immediately complicates even salary comparison beyond practicality, for one simple reason: who decides what work is equal? It’s not possible. That’s why the marketplace exists. Worse is the problem of group comparison: women should make as much as men. OK. Black women should make as much as white women. OK. Should salary then be adjusted for all parameters of race? At what level of resolution? What racial categories are “real”?
