Last night’s vote by the Wisconsin-based portion of the Wisconsin Senate has received enormous attention. The scope of collective bargaining by school district and other government employees has been narrowed, and the state will no longer automatically garnish workers’ wages to pay union dues.

This was the right thing to do. But how much of a difference will these changes actually make to the state’s bottom line? As I’ve noted, the presence or absence of collective bargaining is not strongly correlated with school district spending. Instead, unions have won their massively (42%) above- market compensation through well-funded political action; which brings us to the question of automatic paycheck deduction of union dues.

Without automatic dues withdrawals, will public school unions still be able to afford their fantastically successful political activities? There’s no reason to doubt it. Given the huge compensation premium public school employees enjoy over their private sector counterparts, they have a powerful incentive to voluntarily keep funding the political action that helped win it.

Indeed, we can see this already in right-to-work states like South Carolina. Public school employees there have no collective bargaining rights and there is no automatic union dues withdrawal, but the Palmetto State nevertheless has a teachers’ union and an administrators’ association that have spent large sums of money on political action. It’s worked. Despite not being the wealthiest of states, South Carolina still spends roughly $12,000  per pupil on its public schools, and its public school teachers earn more than the state’s median household income. The teacher and administrator groups have also successfully defeated every legislative effort thus far to open up the state’s education system to private sector competition and parental choice.

The only way to rein-in out-of-control public school spending is thus to give both families and taxpayers an alternative to the government monopoly status quo. Cut taxes on folks who pay for their own children’s education, or who donate to non-profit scholarship organizations that subsidize private school tuition for the poor. Many states are doing this already on a small scale. By so doing so on a larger scale, families will have much greater choices and taxpayers will reap enormous savings.

I wrote about this private school in South Carolina last year. The Voice for School Choice has a new video highlighting the great work of the Eagle Military Academy, which works with many kids the public schools cannot or will not educate.

There’s a lot of talk lately about the transformative power of some charter schools, and it’s easy to lose sight of the fact that many secular and religious private schools have been saving kids all along with no public funds and little or no recognition from the elite opinion class.

We need to open up choice to these schools as well, not just public charter schools that cannot provide the breadth and depth of experiences offered by private schools.

Public charter schools are no substitute for full school choice through education tax credits.

The Ethan Allen Institute has just published a report suggesting that Vermont could save $80 million a year by voucherizing its education system. What’s most interesting is how generous the prospective vouchers would be: $10,000 for K-6, and $14,900 for grades 7-12. How could such a system save money? The main reason is that Vermont was already spending $14,000/pupil on public schools across all grades four years ago. Taking into account the inevitable increase since then and the effects of inflation to 2009 dollars, the state is no doubt spending well over $15,000 per pupil today, so EAI’s ample voucher funding would still cost far less than the status quo.

The only problem is that, as the EAI report notes (see p. 10), Vermont’s state supreme court has ruled against state funding of sectarian schools. So tax credits would be a better option for that reason, among others.
