What is the core argument of this piece? That concentration across industries in the U.S. is increasing? Or that it has been going on for some time? Or that it's best explained not by increased globalization or changing policy regulations, but by technology-driven economies of scale? Or that regulation might explain what's happened for certain industries, e.g., medicine, but not for the economy as a whole? Or ...? Defend your choice.

As for the social implications of all this, answer each of the questions referred to at the end of the article. To wit, given increased economic profits ("surplus," as per the article) across increasingly concentrated industries, should the government seek to redistribute them somehow? If so, how? If not, why not? Should employee-management bargaining mechanisms be strengthened, presumably by increased regulation? Is it necessary to strengthen democratic institutions, given the presumably increased political bargaining power of concentrated industries? If so, how? If not, why not?
