It's all about the money. Not the students-----A $46,000 Spread in the Cost of Tuition Per Degree at Michigan Universities

A $46,000 Spread in the Cost of Tuition Per Degree at Michigan Universities [Michigan Capitol Confidential]:
"Compare the University of Michigan with Michigan State University.
A student taking a 12-hour load will pay about $3,000 a year more to go to Ann Arbor — but a student taking a heavy 18-hour load will pay well over $2,500 a year more in East Lansing.

Almost 85 percent of students who earn a bachelor’s degree from Michigan do so within four years, far more than the 64 percent at Michigan State and an extraordinarily low 11 percent at Wayne State University.

While these differences are revealing, the true cost of going to college depends not only on the number of years attended but also on the risk of dropping out.
It is a fact that over half of the first-time undergraduates (non-transfers) entering seven of the state’s public universities never graduate, or at least not within six years. (The seven are Oakland, Wayne State, Eastern Michigan, Northern Michigan, Lake Superior State, Saginaw Valley State, and the University of Michigan-Flint.)
At Wayne State, a paltry 11 percent of students graduate in the standard four years, and only 32 percent graduate in six..."
