If an education is designed to make students critical of government institutions, public education may make this facet of education impossible due to a conflict of interest. Such a view assumes that teachers cannot operate free from the imagined tyranny of an often laughable state bureaucracy. The view also ignores the role of the government agencies which would regulate private schools that receive vouchers and the impact of business dollars on privately funded educational institutions. If parental choice is a predetermining factor in education, then someone needs to explain to parents that private schools do not have to accept certain students. Even though a parent may choose a private school, the school can turn around and reject the student for a number or reasons which includes the need for specialized services, poor ability levels, improper behavior, etc.
Public schools have to take all students.
It is widely accepted the bulk of private schools that would receive vouchers will be Catholic schools. The AFT has found many Catholic schools to spend the same amount or more per pupil than public schools but does not have to pay for special programs such as special education, lunches, buses, etc. This indicates that public schools can be economically equal or superior to private schools. Another money issue is accountability. Private schools are not held to the same standards as public schools.
