Plenty of people who have psychotic symptoms can live normal, typical lives. I suffer from a psychotic illness (bipolar with psychotic features) and I have a full time career, I have a social life, I can take care of myself and live on my own. It wasn't always easy for sure, and took years to figure out how to live with this illness, but there are lots of people who take antipsychotics and live a normal life, and you'd never know. When people meet me they'd never know I suffer from paranoid delusions at times unless I were to tell them I deal with such things.

I do believe there should be huge increases in medical care and availability for those who suffer from mental conditions and can't take care of themselves though. There's certainly plenty, and homeless people often do have mental issues that they would need help managing. We should help those who can't take care of themselves, but the power structures currently don't seem too concerned about taking care of such people with dignity at all.
