The professional beggars can clear 2-300 a day, tax free. Why get a minimum wage job and have to show up for work clean and decent?
On the other hand, there's a guy at the intersection of 14th St. and the interstate ramp (on the west side) who holds up a sign reading "WHY LIE? - I WANT A BEER." I always give him a couple of bucks 'cause (as I told him) I like an honest man.
If you are so concerned about encouraging employment among the homeless, why not simply ask such folk to pray for you after giving them a few bucks?
