New way to help homeless: Feed a meter

I kind of like the idea of installing machines that take spare change which is then given to the homeless by the city. I never give anyone change anymore because after my experience with the homeless and owning a night club, I know that all it is used for is drugs. Handing someone money doesn't help them get the help they really need. I really believe that panhandling and homelessness in San Francisco is totally out of control. I've done a fair bit of traveling around Asia and Europe in the last few years and I'd say I haven't seen a homeless problem this bad in any other large cities I've seen. Our Mayor hasn't done nearly enough to fight it. Sadly, I do think that the reality of doing something like this in San Francisco is that the machines will be quickly attacked and disabled.
