Valid points, all.

I wish things were a tad more restrictive in the U.S. as they are in Europe. But then, I also take great exception to chiropractors (I prefer to call them chiromancers) here being allowed to call themselves "Doctors" without either a doctorate or a medical degree.

My daughter, just now entering college, plans to structure her education so that she can get a 2-year child psychology associate degree along the way. But that's only so that she can get a slightly better-paying job in childcare to help finance her education while she continues in school to get a bachelor of science and then medical school, with the intent of getting medical degrees in both child psychiatry and pediatrics. Luckily, she has many of the same reservations as I do about the limitations of such 2-year degrees.

For the rest, I concede that my reaction to the study is probably extreme. I suppose I just don't trust statistical studies which seem to have an agenda. If there hadn't been an earlier paper by the two, almost 10 years ago, stating basically the same thing, then I wouldn't be so suspicious of a more recent paper revisiting the same conditions and proposing the same hypothetical conclusions without any other disciplines providing supporting results in the meanwhile. It strikes me more as just restating the same position multiple times in the hope that someone will agree with it, rather than ongoing research which adds to the body of knowledge, or promotes more research.
