I would argue some of the things you list as causes of increasing tuition are the effects of tuition surpluses from additional income from a trillion in student loans.
I'm not so sure about this as a cause. If you look at the costs for colleges that have increased over time, you can start to see where a lot of this money is going. Spending on new and maintaining aging technology is increased. And now you have entire departments like Title IX that never existed in prior school models.
And with expansion, additional management overhead now exists. There is seemly at least a Director of <insert title here> for everything.
