Just as consumers vote with their wallets when they buy cars, furniture or homes, they would spend their money wisely on education. Free choice leads to higher standards, higher quality, better products, innovation, and customer satisfaction. If the customer isn't satisified, he or she looks for another education company (or clothing store, etc.). People are not so dumb that they need socialized education, in my opinion.
Socialized, no. A "standardized" level of competence in education, yes.
If you had a son or daughter in such a school, how would you determine whether or not you're getting your money's worth?
I'm just posing the question as to whom (or what body) would judge whether or not educational standards are being met, and to what degree.
Second, how would people with low incomes fare in such an environment? Would they be able to afford a "Kia" education, while their neighbors across the tracks can buy a "Lexus" education?
