Well..........a lot of it has to do with the notion "I must take a plane and get to this destination". Sure, it is occasionally true, but a whole lot of people on the one hand go when it requires surrendering dignity. And at the same time, none of them reacts to the indignities by organizing politically to put an end. This is what the government sees, the docility, so it will just continue on. As long as nominally free people act like sheep, bureaucrats will act like autocratic shepherds. And you know what shepherds like to do to sheep.
