How do the homeless and drug addicted contribute to a socialist society.?

My job requires me to deal with the homeless and drug addicted daily on the down town east side of Vancouver. I have no qualms with this, but considering I have worked ever since I have been out of high school, and paid taxes every step of the way, how do our homeless and drug addicted contribute to us in a whole, considering the tens of tousands of dollars in equipment they receive daily without charge, the low or free rent, the free needles, and countless other items given with no chance of them turning around. Of course all this while people who have worked thier whole lives are in dept. And lets please leave recycling cans out of this, I see them throw more garbage onto the street then all of thier can pickups put together for the cost of a street sweeper.
