William Baumol is best known for his his theory of "cost disease" of rising costs, common in performing arts, but also education and health care. it takes 4 musicians to play a Beethoven's string quarter and they are not producing any more notes either!
so, why pay them more??
possibly, google found a cure... with is so much free music around why hire any musician at all? and what about techo music? unpaid robots are churning out notes by the truckload.
