Most people are just too tired, too busy with their own lives, too disillusioned with idealistic promises of change, and too fearful of repercussions to try to rock the boat unless they're starving and have nothing to lose.
As long as they've got their bread and circuses, nothing will substantively change.
Even if/when it does change, history shows that we'll probably just wind up with a new boss who's the same as the old boss.
