Phoenix – The issue is subsidization. Figures from the regents show that more than one dollar out of every four paid by students goes back out in the form of financial aid to others. That includes not only scholarships based on need but also tution waivers which are granted for various reasons, like good high school grades. That upsets state Rep. Chuck Gray. He noted there have been a series of sharp increases in the last four years, with tuition for Arizona residents now topping $4,400 a year.
