Former Delaware Gov. Pete du Pont argues for Wall Street Journal readers that Obamacare is bound to have negative consequences for the American economy, health care, and freedom, not to mention the Obama presidency.

Most interestingly, the administration and congressional Democrats seem genuinely surprised that their prized legislation, which was to be the crown jewel of the president’s legacy and the culmination of decades of liberal ambition, simply doesn’t work. Did these folks ever study history, economics or sociology? If they had, they would have known there was little chance of success for their attempt to snatch one-sixth of our economy and thrust it under a complex set of bureaucratic regulations, market disincentives, higher costs and new taxes.

Large government interventions in the market almost always fall short of their backers’ dreams (although not usually this rapidly). Such programs suffer from a common set of flaws, all of which are found in ObamaCare. First, and perhaps foremost, is the hubris inherent in the assumption that bureaucrats in Washington (or Moscow, Beijing or Pyongyang) know better than families, individuals and businesses do what is best for them.

We also often find a certain “looseness” with the facts. There is overpromising at the beginning. Mr. Obama actually promised to provide better health care to more people while spending less money. While some of us saw that was obviously absurd, many are just now coming to this realization. We were told we could keep our existing plan if we liked it, “period.” But it turns out that means “only as long as the government, in its wisdom, decides it’s right for you.” The posturing and spinning continues as the administration tries to inflate the pathetically low enrollment figures. The left’s mindset is that such obfuscation (to be generous) is fine as long as it is deployed in the furtherance of the greater good, which they see as coming only from their policies.

ObamaCare embodies the usual hypocrisy of large liberal programs, as the administration bestows benefits and exemptions on favored constituencies and the politically connected. We see waivers for big labor, relief from inconvenient mandates for congressional staff, and decisions timed to minimize harm to Democrats in the next election. Conversely, those who don’t have politically correct views are ignored or mocked. We see lip service given to conscientious objections to abortion and birth control, but ObamaCare policies that run roughshod over these objections.

Perhaps most disappointing, we can observe in the administration’s handling of ObamaCare a now all too familiar subversion of the rule of law, a fundamental precept of our nation’s founding and of democracies everywhere.
