with you idea that many times people must reach bottom to rebound and improve themselves. Yet I would argue that many, many more who hit bottom simply stay there for whatever reason. It is quite probable that a great many of them could have been productive members of society if they had gotten a helping hand on their journey down. This includes all those listed by daylen in his hierarchy of the downtrodden.
so i guess it is just how you view your place in the universe of your fellow man...you can
1. help by helping
2. help by not helping
it is a personal choice.
