> Are they "just" sucking up to management or are they maybe the only ones who buy the propaganda?

IMO, neither. I don't like this purported dichotomy between "management" and "colleagues/employees". I have seen several of my former classmates and colleagues transition into management roles. Their ideology hasn't changed much in the last 20 years. For example, in the Indian context, their view of Kashmir and the army's role there is pretty much the same as the government propaganda. "Management" did not convince them when we were all still in college, and did not convince them when we were all low-level employees. The people just happened to grow up in an environment where a certain ideological bent was considered "right", "virtuous", etc.
