Tuition tax credits and their possible future effects from the point of view of a supporter are discussed in this paper. The discussion includes a look at the positive effects of homogeneity in schools, maintaining that achievement is higher in private schools, where students and parents share common attitudes toward discipline and education. Also looked at are possible changes in enrollment patterns resulting from tuition tax credits. It is asserted that very few changes would result in rural or suburban areas where people are satisfied with their schools, but that strongest effects would be felt in cities. The possible supply and demand response of education and education consumers is examined. The author concludes that maintaining independence from externally imposed rules would be crucial to preserve the present advantages of private schools. The paper concludes with an examination of divisiveness in American society and whether the concept of a "common schooling" can compete with the concept of "free association." The author recognizes the value of a common schooling but believes that, in a country as diverse as ours, it may not be truly possible. He concludes that an opportunity for some to withdraw to a more homogeneous and effective environment can be provided without destroying our democracy or multiethnic society. (Author/JM)
