I used to be a knowledgeable antitrust lawyer. Back in the day, I prosecuted class-action lawsuits against price-fixers in the bread business and the title insurance industry; I fought tie-in sales and market-allocation schemes on behalf of consumers and small businesses. I used to know the law in these areas and I used it, I think, to positive effect.
But over the years the law eroded, erosion caused by both the opinons of a neglectful US Supreme Court and an indifferent bunch of enforcers in the federal government, from the Department of Justice Antitrust Division to the Federal Trade Commission.
Now, finally, this will change. Perhaps because of a realization that the prior policies have caused the phenomenon of "too big to fail" corporations, perhaps because of the dominating impact of some segments of our economy upon our national wellbeing--we're in for some serious re-thinking of our antitrust policy. It's long overdue, but it's welcome.
