I think you may be misinterpreting what "I" am actually saying. The whole excerpt on drugs was more of a monologue on why I think parts of society are collapsing without people even batting an eye. Nobody wants to ask for help and most people think if you aren't working as hard as them you aren't worthy of a place at the table. (metaphorically speaking) And certain drugs can and do make life easier for the time being... but ultimately they also raise the bar for everyone not on those drugs dealing with the same mental stresses "organically".
I don't think it's very easy at all to say people deserve these problems. I'm an ex drug addict myself. I have seen and experienced first hand "drugs cause people to not have compassion" because ultimately at the end of the day they make you suicidal and you're only worried about your next fix. Not to say I didn't still have a kind heart but I couldn't help myself so how was I going to help someone else?
The quote was from my own personal experience being homeless and on drugs. I'm not trying to diminish or take away from anyone else's struggles. Saying someone can't be sad because other people may have it worse is like saying someone can't be happy because someone else may have it better.
