Jerry, in general I can agree. But a goodly number of people understood "carrying capacity" long before anybody ever heard of a game department. For that matter, even TP&WD didn't understand it until the 1970s. Such knowledge was commonplace in my family in the 1800s.
It's not always a matter of "thinking" about knowing best--or at the least, better.
Based on sixteen years of employment in government, I guarantee you that such employment does not create wisdom.
