I was a part-time college instructor and agree. Some of the smarter students IMO were the homeless, poor, and others who paid little to nothing. I taught a homeless ex-Stanford professor who was well known in the community and he was very sharp. The rest were mostly under no illusions about what they were there to do: Get a degree or certificate and move along. It doesn't take much critical thinking to recognize a stepping stone like college for its most practical applications: Degree printer and networking system. I made many good friends of students who were critical thinkers. I also saw really sharp critical thinkers get absolutely torpedoed by life events and poor decisionmaking; these were often the 4.0 high school students who thought they could cruise. It was sad to have to demolish their record. I wish I could read TFA, as I wonder how my experience squares with the point of the article.
