I understand your overall point, but I did think it was amusing that you seemingly managed to blame illegal immigration for increasing tuition costs.
Here in Texas, we have had one of the largest (if not the largest) tuition increases in the country recently. My tuition shot wayyy up from when I was a freshman to when I graduated in December.
Here, the Texas legislature first decided to slash the amount of funds they were giving to the institutions, including UT, and then set the tuition rates higher. Then, they decided to slash the funds even more, but also to deregulate tuition, allowing the UT board of regents to set tuition prices. As a result, all of the costs that were previously going to tax payers were now going directly to the students.
This could be a good thing (making the people who actually use the service pay for it rather than all tax payers in the state pay for it), but taxation levels within the state didn't go down - they just put that money to other uses.
