I don't think too many people are "thrilled" with the idea of anyone abusing government aid. I think, though, too few people see that so many ways the government sets things up actually a) screen out the most deserving and responsible of people, and b) invites those who aren't above abusing the system (that, in fact, does invite it). I'm not defending the abuse or the abusers - only pointing out that the government often invites it.
Having said that, though, it's not just a matter of the government inviting sleazy people to abuse programs. It's also a matter of programs being set up in a way that can almost force non-sleazy, "genuinely legitimate", people to do things that might be considered "abusing the system" when, if things were set up in a way that more realistically and effectively helped individuals and families, they never would engage in "iffy" use of government money. An inadequate understanding of the true, and less obvious, needs of individuals/families in needed of assistance (among other things); and the automatic assumption that people/families who need assistance are a) in need of education or one kind of another, b) are lazy people who are out to get something for nothing, and c) that meeting some minimal level of physical needs (food, shelter and heat) is enough for a person to get on his feet; are, I think, the main reasons government programs are so useless to so many. As a result, people often "take matters into their own hands" in their aiming to meet the needs programs don't meet, by using money intended for one thing for something else.
