These days we have advanced medication which can cure I'd say 95% of all mental illnesses. So these people would only be in hospital a few weeks to get onto the right medication.
Then get them into temporary housing - not a shelter where they have to beg/pray to eat, but just a normal house.
They should ideally be on social security while ill, but work if they are able.
While I'm not a psychiatric professional, I do associate with several people in that field, and I'm calling shenanigans on your numbers. I'd say:
"These days we have advanced medications, which can help with some of the symptoms of perhaps 25% of mental illnesses. Effectiveness will dramatically vary by person, and only works if the person continues to take the medication as directed (something that is very often outside the ability of a mentally ill person on their own). Also, many of these medications can cause health issues, addiction, toxicity, interactions with other medications and drugs, and need to be monitored on a frequent basis by a medical professional in order to fine tune the dosage, and look out for early warning signs of serious side effects."
