ABSTRACT: We propose to study the causes of evasion along three basic lines, namely: the myopia or ignorance of public policy managers who restrict the supply of educational services; the intrinsic lack of interest of parents and students about the supply of education, be it for its perceived low quality or their ignorance and myopia about education’s potential impacts. A third line is the income or credit market restrictions that stop people from enjoying the high returns of education in the long term.
