By turning most of health care into what amounts to regulated utilities, Obamacare forced mergers and acquisitions within the sector.

A recent Wall Street Journal story highlighting a new antitrust investigation against the nation’s largest health insurer represents a variation on a long-standing theme. In this instance, as in prior occurrences, the Justice Department and federal officials are trying to undo the harmful effects of a law — Obamacare — that has led industry giants throughout the health sector to consolidate.

Recall that, four election cycles ago, then-candidate Obama promised in 2008 that his health care plan would lower premiums by an average of $2,500 per family. That premiums continue to rise unabated shows the failure of Obamacare by Obama’s own standards — and the anti-competitive behavior the law has engendered explains why. //

But Warren gave away the plot by citing the title of a blog post in her letter: “How Obamacare Created Big Medicine.” It’s the perfect summation of why, as Donald Trump said in social media posts around the time of Warren’s letter, “Obamacare sucks.” And the Justice Department’s investigation into UnitedHealth provides an implicit admission that even President Biden and his administration agree.
