Steven Greenhut, as seen on Reason.com. I endorse this view.
When it comes to problems in the public schools, my conservative friends are right on target with their critique. These schools often do a poor or mediocre job performing an important function. That's because they lack competition and are funded by political priorities rather than customers. Teachers' unions have undue sway over the entire process. They make it nearly impossible to fire even grossly incompetent teachers and that small percentage harms many students. Those same unions drive up unsustainable benefit costs.
Like everyone else, conservatives appreciate teachers—but they realize that the current taxpayer-funded system needs many reforms and more competition. There's nothing wrong with pointing this out, which is a reality in any government-funded, union-controlled monopoly anywhere in the world.
Yet when it comes to another type of taxpayer-funded, union-controlled monopoly, conservatives lose their sense of perspective. I'm referring, of course, to local and state police agencies. The same dynamic described above works there, too. Police agencies are bureaucratic. Unions protect the bad apples and make it nearly impossible to fire anyone—even officers caught on video misbehaving or being abusive to the public. The agencies hand out unsustainable benefits and have some bizarre spending priorities (tank-like vehicles, etc.). They are secretive and insular. They use asset forfeiture to grab the property of people never convicted or even accused of a crime.
