That's the point.
Everyone has had enough when it comes time to quit. The border patrol gets paid to not do their job. They’ll shine it on while their concerns are blown off by their bosses who are the sheep. One can always quit the military when their enlistment is up but the lifers are stuck keeping their mouths shut. Going through the motions keeps people in line. How many FBI agents would like to hang their bosses for their crap? You end up giving minimal effort and their all ok with it.
