Charles Krauthammer‘s latest column examines the national implications of this week’s Wisconsin recall election.

Tuesday, June 5, 2012, will be remembered as the beginning of the long decline of the public-sector union. It will follow, and parallel, the shrinking of private-sector unions, now down to less than 7 percent of American workers. The abject failure of the unions to recall Wisconsin governor Scott Walker — the first such failure in U.S. history — marks the Icarus moment of government-union power. Wax wings melted, there’s nowhere to go but down.

The ultimate significance of Walker’s union reforms has been largely misunderstood. At first, the issue was curtailing outrageous union benefits, far beyond those of the ordinary Wisconsin taxpayer. That became a nonissue when the unions quickly realized that trying to defend the indefensible would render them toxic for the real fight to come.

So they made the fight about the “right” to collective bargaining, which the reforms severely curtailed. In a state as historically progressive as Wisconsin — in 1959, it was the first to legalize the government-worker union — they thought they could win as a matter of ideological fealty.

But as the recall campaign progressed, the Democrats stopped talking about bargaining rights. It was a losing issue. Walker was able to make the case that years of corrupt union-politician back-scratching had been bankrupting the state. And he had just enough time to demonstrate the beneficial effects of overturning that arrangement: a huge budget deficit closed without raising taxes, significant school-district savings from ending cozy insider health-insurance contracts, and a modest growth in jobs.
