There is a bizarre irony at work here. Both the right and left are convinced ObamaCare will eventually become popular if implemented. Conservatives fear the “ratchet effect,” a term coined by the great libertarian economic historian Robert Higgs. Once government expands, goes the theory, reversing that expansion is nearly impossible. Liberals have their own version. They point out that once Americans get an entitlement — Social Security, Medicare, etc. — they never want to lose it. They hope that if they can just get Americans hooked on the goodies in ObamaCare, they’ll overlook all the flaws.

There’s a lot of truth here, to be sure. But it’s not an iron law either. Sometimes, bad laws get fixed. It happened with Medicare in 1989 and welfare reform in 1995. Many of the boneheaded laws of the early New Deal were scrapped as well.

Republicans should have a little more confidence in their own arguments. If you believe that ObamaCare can’t work, you should expect that it won’t. Forcing a debt crisis or government shutdown won’t kill ObamaCare, but it will give Democrats a lifeline heading into the 2014 elections, which could have the perverse effect of delaying the day Republicans have the political clout to actually succeed in repealing this unworkable and unpopular law.
