This argument assumes two things: First, that private schools discriminate more in selecting students than do government schools and second, that government schools are open to all students. But neither of these assumptions is necessarily true. Government schools do not accept every student, and many private schools in fact accept a wide range of students. In addition, parents empowered with choice can select from among a wide range of schools, private or government.
The Facts:
The current government assignment system already makes choices for parents.
Private schools are not characterized by exclusivity.
School choice provides greater opportunity for all parents and children.
