Joe's rationale is that he deserved welfare "because he paid into it."
Contrast with:
Joe: "Basically it's wrong to take money away from people who work hard. There's guys out there who make their obligatory one phone call a week, supposedly looking for work, and then they go to the welfare office, looking for a cheque. My money shouldn't go towards them. They don't do anything. They don't contribute to society - they take away from it. And I have a problem with people like that."
