Yes but not really. It's mainly about the kind of treatment you face when you get on the wrong side of the airport machine, and as such it's exactly what you're implicitly threatened with if you step out of line.
Horrible airport, avoid at all costs.
People attempting to enter illegally, not for failing to down drinks like it's a frat house...
Ok, now take that figure and deduct tax, housing, food, utilities and so on - how much do you think is disposable/saveable? And then take the typical cost of a last-minute replacement flight and compare those two numbers.
it would be incredibly inconvenient, and maybe missing other parts of a full vacation would set them back, but thats not the only reason people buy flights
