Social science faculties (the political scientist, economist, sociologist and many of the historians) tend to be liberally oriented, even when leftists are not present. This is not a criticism per se, as the need for liberal thought is essential to a balanced viewpoint. The difficulty is that “balance” is conspicuous by its absence on many campuses, with relatively few members being of conservatives or moderate persuasion and even the relatively few often being less articulate and aggressive than their crusading colleagues.
One thing that I find interesting is that he provides no stats to back up his claims. His claims are mainly based on personal perception. He still has yet to quantify the effects his so called "crusade against business" has had on actual businesses. While I will acknowledge that this is a memo to his friend it, so he might not have felt the need to include stats which are seen in more formal settings.
