I'd wager most of the people in the program aren't rich, they just have jobs that require them to travel a lot. We're talking Accenture consultants, not bank execs.
It isn't that most of the people in the program are or are not rich, it is that most of the rich in the country are in the program. In other words -- anyone who is (a) likely to be annoyed by the inconvenience AND (b) powerful enough to do something about the inconvenience has been co-opted by PreCheck.
