Them: It is the same everywhere. The problem can't be solved.
Me: No, we don't have homeless in Sweden, beyond the few drunks or drug addicts.
Them: Ahh! But you have such high taxes!!
Me: Yeah. Welfare isn't free, you know. But the problem is solvable. Saying it isn't because it requires high taxes pretty much just makes you a greedy bastard.
Them: No, no, no. We believe private charity can do the job better. I give to private charity! I'm not a heartless, greedy bastard.
Me: Really, yes you are. Clearly the problem requires funding beyond your token private charity provisions. Or it wouldn't exist anymore. As we have a concrete example of it being done better by government elsewhere, your belief in private charity is pretty much demonstrated false.
Them: Yeah, but your taxes. They are so high...
