Thought control is a ubiquitous phenomenon that our ruling masters exercise over every institution in society, but their application of it is particularly strong in a core capitalist curriculum like economics. As Ruccio points out, economics departments of institutions of higher learning usually do not permit any kind of "alternative" views on economics. He cites a recent exception to this rule in which the U. of Glasgow permitted for a time an unorthodox lecturer in their department--but it was not to last.
Ruccio's experience with students and colleagues was particularly disheartening for me:
No matter how many stories I tell them about thought control in economics, students and colleagues in other disciplines simply don’t believe me.
