I like to think of it this way. What if we made citizens pay for public high school like we do in college? There would inevitably be some children who would not be able to pay for and afford to go to school for all four years, if at all. Would it be wrong then to deny a child the necessary educational background provided by a high school education? Why does it make sense that a high school education is valued higher than a college education? Are both not necessary, in today's day and age, to succeed and compete against your peers? I believe the very premise the public institution was founded on supports the fact that making college available to more people is rational. Plus, it would be in the best interest of the country. By making education more available to all people, those in the the lower socio economic classes, who typically cannot afford a quality college education, have the opportunity to rise out of that class by performing in high school and getting accepted into a public university. That way a young man or woman isn't subject to the success of their guardians, but is evaluated based upon the quality of the student.
