These types of defenses always seem to come from fully entrenched Academics who have a cushy tenured job. I have to wonder if you polled 100 PhDs in a variety of liberal arts subjects, especially after they have been out of school for 5 years, the points would be considered valid.
I do not debate the importance of a wide base of knowledge. I do, however, object to using tax payer money to crank out millions of college grads with no job skills and little prospects of paying their own way in the world. For a reality check, tag along on a college tour at a randomly selected college. You will see first hand what is being sold these days. 95% is leafy campus, beautiful people, great football team, 'social responsibility', Nobel prize winners (whom you will never see or hear from), cafeteria, and Greek system. They use the word 'diversity' a LOT, but there really isn't much.... mostly Asians and Whites.
My son attends one of the 'other' types. Before the college tour, we saw nice kids in good physical shape, and seemingly happy. The intro presentation started with the following statement "our goal is to provide a great education, with an undergrad degree in 4 years leading to a job in the selected major course of study". And. they are doing that. Compare with a tour at another college in the same public system where we were bombarded with political correctness and reminded of the exact numbers of minorities at the school. Then, we were told how they have the biggest Gender Studies department in the country. The parents looked at each other, and a number of us started laughing out loud. Things went downhill from there.....
If we are truly trying to create a more 'aware' student, then lets start with better reading, writing, and math skills. And, lets dump tenure in the early grades so we can focus on TEACHING, not politics. But, hey, the teacher unions are now the number one campaign contributor to the current administration in Washington.
