College instructors write like high school kids. There are very few professors left, actually.
A recent movement back to using professors is taking place. More and more colleges are requiring a PhD to teach. However, the quality of instruction has not improved.
In the liberal arts, it does not take much to get a PhD these days.
That is because more and more PhD awards are useless and worse than useless especially in the "soft sciences" like sociology, women's studies, literature, etc.
College "education" in anything but the actual sciences and engineering has become a cruel joke meant not only to indoctrinate into intellectual and moral ruin but to extract money from the rubes who think they area getting any thing for their massive indebtedness - which they now expect the government to amnesty, which it ultimately will do in exchange for their slavish support.
But the biggest suckers are the taxpayers who pay for this outrageous scam and don't in return burn these wicked places to the ground and tar and feather their professors and administrators for the theft and murder of the future and morality of their children and society.
