Competition Helps Public Schools

Opponents of private school choice like to point out a recent study that purports to show public school students doing as well or better than private school students on the National Assessment of Educational Progress standardized test.
Besides being a flawed study, the opponents of private school choice are missing the point. It isn't public schools vs. private schools, but rather government monopolies vs. competitive education markets. When the government school monopolies are introduced to competition, it has been found that "competition is in general good for the public schools."
Opponents of private school choice, like Al Gore, are therefore wrong to say that money being "drained" from public schools via private school choice will harm public schools. Private school choice does just the opposite, it helps the public schools.
