I want people to live in Milwaukee, and so I want school options to be available to them. That means private and parochial school options, and public schools would get better so that people actually would want to be in them. It's just that there are not enough of them. Overwhelmingly, the choice students are minority. Vouchers are not a way for white people to flee the system.
Private schools are just as integrated or more integrated than the public schools.
The only segregation that worries people is if it's in a private or religious school. It's an argument for maintaining the monopoly, with the employees of the system being the number one priority. They're important, but their interests aren't as important as the outcomes for the kids. It's just like the sugar industry in the United States. They're afraid of competing, so the price of raw sugar in the United States is over twice the world price.
