I think it's really just a matter of numbers. Lots of abusive programs have been operating for decades in this country. Right now, WWASP has been so successful at marketing that they've got something like 5k kids under custody most of the time. I don't know if that's an accurate number today, but suffice it to say that they're messing with a LOT of families!
Now, most people get out of these cults one way or another and the last thing they ever want to do is to set themselves up to have to think about it, talk about it, relive it day after day for as long as the defendants can draw it out. Even if they're willing to do that, if their parents are not going to back them and might well either send them back or change the locks on the house, they might not want to chance it. Then there are the program policies that make it very difficult for program survivors to stay in touch with eachother. If you call up the school or WWASP and ask how to get in touch with someone, they won't tell you unless that person is 'in good standing'. Even then, as I understand it, they're extremely paranoid about former clients getting together to compare notes.
WWASP is getting attention right now because a lot of WWASP kids and parents have come upon the right circumstances so that pursuing legal action makes sense for them. By and by, I think the others will come under similar scrutiny as more of the public gets the word on WWASP.
Hold on, my friends, to the Constitution and to the Republic
for which it stands. Miracles do not cluster, and what has
happened once in 6000 years, may not happen again. Hold on to
the Constitution, for if the American Constitution should fail,
there will be anarchy throughout the world.
