College costs have risen dramatically over the last several decades. In many cases, it's difficult to find a college where per-student costs are under $20,000 each year. Most often, tuition doesn't measure the true cost because taxpayer and donor subsidies pay part of the expenses. While costs are rising, education quality is in precipitous decline, particularly at the undergraduate level. Part of the reason is the political climate on college campuses, where professors use their classrooms for proselytizing and indoctrination and teach classes that have little or no academic content. Let's look at some of it.
