There's a ghastly number of people who are aggressively ignorant assholes.

The point is that we don't have people sleeping on the street for a lack of... anything, really. Including beds. The point is that, when nearly everything is run for-profit, and it's even slightly more profitable to let people suffer and even die, then people will suffer and die. We do a better job selling beds than we do making sure everyone has a bed to sleep in. We could make sure everyone has access to a warm bed, shelter, food, medicine, etc., but we don't, and it's less and less acceptable to just accept the status quo just because it's the status quo. If someone thinks the status quo is defensible, it's on them to defend it.

That doesn't mean the mattress seller is evil, or (and I can't understand the logic in one of the other comments) that wanting people to be housed makes you a hypocrite if you have your own housing. And the absolutely shameless comments that openly admit they won't (really can't) explain their position, but are going to condescend anyway.
