Mr. Cassidy is more honest than the politicians whose dishonesty he supports. "The U.S. government is making a costly and open-ended commitment," he writes. "Let's not pretend that it isn't a big deal, or that it will be self-financing, or that it will work out exactly as planned. It won't. What is really unfolding, I suspect, is the scenario that many conservatives feared. The Obama Administration . . . is creating a new entitlement program, which, once established, will be virtually impossible to rescind."
Why are they doing it? Because, according to Mr. Cassidy, ObamaCare serves the twin goals of "making the United States a more equitable country" and furthering the Democrats' "political calculus." In other words, the purpose is to further redistribute income by putting health care further under government control, and in the process making the middle class more dependent on government. As the party of government, Democrats will benefit over the long run.
This explains why Nancy Pelosi is willing to risk the seats of so many Blue Dog Democrats by forcing such an unpopular bill through Congress on a narrow, partisan vote: You have to break a few eggs to make a permanent welfare state. As Mr. Cassidy concludes, "Putting on my amateur historian's cap, I might even claim that some subterfuge is historically necessary to get great reforms enacted."
