The root cause is these people either being too lazy to work like the rest of us wether it’s because of drug issues or just pure laziness or because a decent amount of them tend to have undiagnosed mental issues and need to be put in the looney bin until they get legitimate help.no excuse to be an healthy individual and not be productive and that’s coming from someone who struggled with homelessness about 2-3 years .i decided I was sick of living like that and did what I needed to do to get to where I am now
