A good article about the problems with public schools

Andrew Coulson has a long thoughtful article: A Less Perfect Union. 

It starts:

----------
Student achievement at the end of high school has stagnated or declined, depending on the subject, since we started keeping track around 1970. Over that period, the cost of sending a child through the K-12 public system tripled, even after adjusting for inflation. Public school employee unions, the National Education Association and American Federation of Teachers, are partly to blame for this, but the attention focused on collective bargaining in particular has been misplaced. The unions' success in driving up costs and protecting even low-performing teachers stems less from their power at the bargaining table than from the monopoly status of their employer. Taxpayers, and most families, have no place else to go.

I do disagree about families having no place else to go.  A large reason for the dramatic increase in the number of children being homeschooled is because more and more parents and unwilling to allow government schools to hurt their children.
