I am not sure exactly, but a plausible interaction would be: Tax benefits cut forcing more students to seek financial loans for student expenses. Conservatives further protect lending institutions (and punish students) by making student debt one of the forms of debt not clearable by bankruptcy creating an artificial safety for lenders. Student loans are now a low risk lending market so lenders relax requirements for loans. Now students have greater access to financial loans of larger size so Universities are able to raise tuition without impacting operations/enrollment. This is obviously a contrived line of reasoning, but the point is that there is a complex interaction occurring resulting in what I (personally) would consider market failure.
