Comment: This statement strikes me: "those privileged to be housed.."
I wouldn't call dragging my assets out of bed and into the cold then spending 8 or 12 hours a day busting my butt, dragging my tired assets home to do it again 5 or 7 days a week a privlege. Somewhere along the way I realized that I would have to make choices. Some of my friends would dash off for three or thirty day weekends, I had to work. I had to work.
To those who are able bodied but are enjoying the freedoms of childhood into their twenties, thirties, and beyond, I have no sympathy and do not wish to support. To those unable to help themselves, we can do more. 
Maybe we'd have more to give if we stopped giving to those who just take...
