This is a great attitude to make yourself feel better, but it's not terribly productive if you can't produce some science yourself, or if you are, you know, any way inclined towards respecting humans' individual choices. Economists and sociologists, who are much better at science than educators, try to avoid making the mistake of knocking peoples' choices unless they're obviously irrational, because forcing peoples behavior to be a certain way in the name of "science" is an easy way to be disastrously wrong.
Letting parents choose schools is not any more respective the choice of the individuals most directly affected than having government decide on the school.
