Agree that we need to take real action to curb homelessness and help the mentally ill. Addressing homelessness is usually done by creating free/inexpensive housing. The latter would be solved with true government available healthcare.

The problem with implementing either is a sizeable percentage of the population won't tolerate people getting stuff for free, and will vociferous oppose and vote against their tax money going to "moochers". The "they bought filet mignon with food stamps" style memes would be everywhere.

So we'll probably end up doing what we always do. Give more money to cops and hope they can sort it out. (Hint: At $11B, it's the most expensive PD in the country, and they are not equipped to solve homelessness.)
