Oh, dear. Really? I take it you're not a college-level instructor.
With the exception of tenured faculty (btw, tenure is not quite as inviolable as some think), professors and instructors typically remain employed and are promoted based, in part, on student evaluations.
[Nowadays, a prof who gave average grades (i.e. Cs) to average students in her/his course would likely find her/his academic career coming to an early end--regardless of the actual quality of teaching, commitment to/availability for students, etc.]
Faculty are also under pressure (by administrators) to pass students, because students' failure to graduate from the college in X years affects the college's ranking. Students who fail (and their parents) give administrations hard times; faculty who are willing to fail students are not looked upon (by the admin) with favor.
And this doesn't even touch on the pressures in public colleges, where the city or state has some definite ideas about the role of the college (which--typically--is primarily to produce degree-holding graduates).

The simple fact is that a majority of Americans (60% or more) just don't have the mental firepower to be successful in a four-year college: they end up with no degree, or a useless one, and a mountain of debt.
But more than 60% attend college anyway, and in the great majority of colleges and universities, the faculty are expected--in some fashion--to take up that slack.
