Will monopsony become the new monopoly, ferreted out by jealous market participants and powerful government agencies, in order to hobble market leaders and reign them back to within a competitive distance?  Will Apple pay for its buying power in this decade the way Microsoft did for its alleged selling power in the last?

Incidentally, although I just learned the word today, this concept is what always worried me about the federal prescription drug program and even Medicare/Medicaid in its various forms:  when the government becomes essentially the only buyer of drugs and medical services, they won't have to legislate price controls.  They'll be able to bring them about by brute force.
