One needs to keep that approach in mind when judging people who are within a system that one as an outsider critizises. There may be people in there who try to change it for the better.

A historical example is the French Revolution. Many people who tried to reform from within still got their heads chopped off. In fact, everybody but the most radical did, and even those ended up paranoid about one another.

Other examples are former socialist eastern countries. Just because somebody was state employed with decision making authority does not mean they were pro-dictatorship. Many realized that to improve things they'd need to work within the system instead of openly opposing and ending up in jail.
