being in a program in no way helps people through rough patches later on. In fact, programs focus on and imbue a sense of powerlessness if absent a strong authority, or under fire by an authority figure. it's almost clockwork orange-like. HLA really drives in the notion that one is powerless to change oneself and must rely on a higher power; that higher power psychologically imprinted into HLA student's minds as being HLA itself. Through tactical use of the restrictions and fallout systems, the notion that HLA is god himself is subconsciously imprinted into every kid's mind. HLA becomes a force which controls every aspect of the kid's life; please it and you will be rewarded, anger it and you will be punished, and sometimes just as with the real god, you are subject to random acts of cruelty.
one of the lasting effects of programs is chronic psychological damage. PTSD and related anxiety disorders seem to be most common, followed by depression induced by program-connotated triggers.
Some of my friends from the program have developed serious issues with anxiety directly as a result of their experiences at HLA. anytime they are put into a position of powerlessness e.g being yelled at by someone bigger or more powerful than they are, or when doing something an authority figure disapproves of, they break down into an extremely paranoid and anxious state. one kid i know even has an ulcer developed almost entirely from constant, baseless fear and paranoia imprinted into his mind at HLA.
quite a few people i know cannot function independently. they require constant attention and routine along with a strong authority presence in their lives. without it, they kinda wallow around drinking and doing drugs like russians after the fall of communism.
so your point about kids being more in control of their own lives as a result of the program is mute. They may have a tougher skin as far as their ability to withstand abuse; they are masters of "checking out" - they did so for 18 months - but they are most definitely not better off.
