Politicians were piling on this week to criticize the deal, including Donald J. Trump; Tim Kaine, the Democratic nominee for vice president; and Senators Bernie Sanders of Vermont and Al Franken of Minnesota….

A younger generation of antitrust scholars who are rethinking the nation’s fundamental approach to antitrust law may prove even more influential.

“The antitrust system as it stands is focused on prices to consumers, innovation and efficiencies,” Mr. Wu said. “That reflects the triumph of the University of Chicago school of economics. But there’s an older tradition, embodied by Supreme Court Justice Louis Brandeis, that says a concentration of too much power in too few hands is bad for democracy and bad for consumers.”

It’s hard to imagine a more widely reviled piece of legislation than the nearly $1 trillion farm bill. Its widely ridiculed handouts to wealthy farmers and perverse incentives have long united liberals concerned about the environment, conservatives upset about the deficit and market-distorting subsidies, and just about everyone concerned about basic fairness.

Just about everyone, that is, except the powerful farm lobby and its allies in Congress, which every five years or so since the Depression has managed to fight off any meaningful reforms and actually increase farm subsidies.

And now they’re doing it again…. many of the same legislators up in arms about government spending and welfare abuse nonetheless voted for an increase in federal subsidies to wealthy farm interests.
