I don't think it's impossible to raise social class, some doomsayer predictions to the contrary. At least, I think that it is possible
to go from, in GURPS terms, Poor to Average, or Struggling to Comfortable. (Anything beyond Comfortable is another matter.)
However, it's a bit like Finding The Right Psych Meds For You, if you are one of the people who is in need of such things. There are many
options out there. However, as far as the usefulness of any given option, if I remember my reading correctly the best
numbers I've seen (assuming correct diagnosis and yadda yadda) for a specific drug working to provide significant symptom control without intolerable side effects is about 40%. The chances that you'll get that drug on the first try...not necessarily so good, especially since that 40% number is for an oldie-but-goodie (lithium to treat Bipolar I) that doesn't rake in the dough for Big Pharma. And well, some drugs make things much worse if you attack the wrong problem - say, your "depression, insomnia and anxiety" is really bipolar disorder, or your "treatment-resistant atypical depression" is really hypothyroidism. People can also have drugs not just not work but make things actively worse - paradoxical reactions, allergic reactions, serious
weight gain (or loss), and other truly unacceptable physical consequences are all possibilities.
And of course, because of the horror stories out there about particular drugs and their possible side effects (the 1-in-3000 chance of getting hit with the Lamictal Rash, the prospect of gaining 100 pounds on Zyprexa, the you'll-never-have-or-want-sex-again-and-
stuff horror stories of Paxil, etc etc) or because a given person thinks that "solving problems" with medication is ALWAYS morally wrong, some people who can barely function are continuing to barely function out of fear that they will lose what little function they have, or lose their pride in "making it on [their] own."
But anyway, this is about being poor, not about psychopharmgeeking.( and when talking about poverty, most of these issues have parallels )
