handouts

There's this freeway offramp right by our apartment, and someone put up a wooden sign that says, "Handouts support homelessness."  People occasionally spare change there.  The sign has been up for months.  It's not super noticeable.  But it pisses me off.  I think their point is that if you give money to homeless people, they stay homeless, and if you refuse to give them money, they'll be forced to give up homelessness and get a job and magically turn into model citizens.  Of course that's bunk--it doesn't work that way.  But I don't see why the powers that be allow the sign to stay up.  I guess they agree with it, so that vandalism stays? 

There was a beautiful street art painting up that was painted over within days, so why does this wooden sign on the fence remain?
