I'd object to the framing of that a bit. the impulse is to 'solve' or at least deal with the problem -- but why is there a problem in the first place? our answer goes all the way back to Marx's 1844 papers, "economic and philosophic manuscripts". an increasingly rigid division of labor forces the individual to turn himself into a marketable commodity. he lives to work, works to live, rather than both at once.
if in 2015 man is in fact more 'ill' than he was in the past it's because of this. hand-in-hand with this, the range of acceptable behaviors gets smaller and smaller the more rationalized and commodifed the society becomes. in an agricultural society, if Jimmy down the road heard voices at night, but still grew his grain, he was Jimmy down the road who had a habit of making noise at night. today he's a "paranoid schizophrenic."
an instructive case is that of
Rube Waddell, one of the best pitchers of all-time, who today would've been condemned as mentally ill. he would run off the field to chase fire trucks, was attracted to mirrors as to a magnet, etc. in 2015 he'd have been pumped up with amphetamines "for his own good". in 1905 he was allowed to be himself.
the case is only magnified in the case of an advanced military, where your average soldier has to be programmed and deprogrammed to such an extent... we all know the problems with that.
