This is a bit of a tangent, from the idea of "people that would not work if you handed them a job on a job on a silver platter." Here's what I've come up with as a way to tell the people who are really just down on their luck from the handout-grabbers...
Set up farms with simple but adequate housing (including family cabins as well as dorms for single people), and free bus service to these farms. Anyone that says they need the help can move in, and anyone can move out any time they want to (although if they try to move back in very soon after moving out they have to explain what the heck happened). The idea would be for it to be as self-sustaining as possible, so there would be agriculture work involved, food preparation, maintenance on the buildings, maintenance on the machines, cleaning, and probably some child care; it would be communal, in a voluntary way, because everyone would get to use what was made (and ideally they would know how they helped make it, whether is was "I cooked the spaghetti sauce" or "I picked the tomatoes" or "I watched the rugrats so their parents could pick the tomatoes," so there would also be some pride involved, which would boost self-esteem and reduce waste).
The only rules to live and work there would be...no drugs, no alcohol or drunken stupidity on-site (those of age could drink off-site as long as they don't cause trouble when they come back), no reproducing while you still need help with basic living expenses (i.e. no sex or use birth control--pregnant ladies wouldn't be required to get an abortion), and everyone puts in a fair shift of work to keep the place up depending on their abilities and how much there is to do (kids and teenagers still in school would have an amount of work that would be like kids anywhere have for chores, and would have to keep their grades up to the best of their abilities; healthy adults would have an amount like a full workday).
So that people wouldn't get in and then get permanently stuck there, they could also take classes to improve their skills so they could find a good job and leave. General education, career training, and parenting/household skills classes would be offered, possibly in partnership with a local community college or trade school, for anyone to take during their downtime and work schedules would be flexed so that people could take the classes they needed or within reason wanted (wanting to take a specific class because it's easy, like basic math when they already know it = not reasonable; wanting a specific class because they're interested in the stuff and don't already know it = reasonable). This would inevitably involve bringing in some teachers from the outside, although some classes, like basic math, reading, ESL, GED prep, etc., could probably be taught or tutored by people who were there because they'd been laid off.
Undoubtedly everyone there would be eligible for Medicaid because they're there in the first place because they have little or no income. Someone could help them do the paperwork for that when they check in, so that they can see a doctor any time they need to. First aid would be available on-site from someone who did about the same things as a school nurse would--this person might also teach first aid classes.
Obviously you'd have to have the right people running it, for it to not become a corrupt mess, as with anything involving large numbers of people. But, done right, it could get a lot of people off the streets, taken care of, and on their way to having a good life.
