Liberalism's key principle is to redistribute wealth from the haves to the have nots. That takes money from the entities with the greatest potential to improve society (for example, corporations that create jobs, invent life-saving medicines, etc.) and redistributes it to the people, whom on average, will never contribute more to society than to hold a menial job.
Marty NemkoBehaviorism is sometimes criticized as encouraging unethical behavior. For example, most organizations offer rewards for increasing revenue and threat of punishment, perhaps firing if you don't "make your number."

Marty NemkoI believe that a core problem with undergraduate education, especially at research universities like Harvard, Stanford, NYU, etc, is that most teaching is done by PhDs, who by temperament, training, interests, and rewards are researchers first. So they spend most of their time and energy probing a snip of a field's cutting edge. In my view, the attributes needed to be a transformative undergraduate instructor are pretty orthogonal to that. It would seem that undergraduate education would be superior if there was a separate track for teaching faculty.
