Remember when 11,000 air traffic controllers were all fired by Reagan in August of 1981? While it is true that government jobs have a reputation of being secure, I'm not at all convinced the government is telling the truth about that security. And there are other ways to persuade government employees to carry out policy set by the department heads, who are carrying out policy set by the president, who is carrying out policy set by his handlers, who are carrying out policy set by whoever controls the money. The money still does the talking. How about being given undesirable assignments, or being passed over for promotion continually? I've seen both happen. When sociopaths are involved in leadership positions, they will find a way to get their underlings to perform as desired. Sure, there can be exceptions, but the carrot and the stick are mighty effective. I am reminded of General Montague Winfield, who I suspect was promised some important perks if he just didn't show up for work on the morning of September 11, 2001. I've dealt with this character, and I'm convinced from his behavior that he's a detestable sociopath, adept at charming and fooling just about anyone. Psychologically, he's much like Bill Clinton.
