The problem is that there's so little money in academia. In the US, state support for public universities has plummeted in the 21st century. In the last state I lived in, the state university near me went from providing over 75% of teaching costs to under 25% in less than 20 years. Tuitions have risen, but it's important to understand the sticker prices are usually discounted with financial aid. If a university raises tuitions by an amount x, they are usually brining in less than 1/2 x new funding. Ironically, reducing university funding leads universities hire more administrators, as they attempt to replace lost funding with donations or indirect costs.
