I really admire these charitable and heroic efforts to help. But I can't help thinking, that the problem of homelessness should be attacked via it's root cause, which is a society does not care for the poor or sick, in a very Darwinian 'survival of the fittest' kind of way.

The obvious solution is to collect more taxes, and to help those in need, be it due to poverty or mental health issues. That would mean paying for housing and providing free healthcare.

So, if you really want to help, consider the idea of a more social state, and be willing to pay higher taxes.
