They are living for free with someone else, eating their food. Or.they are abusing welfare to have a house even though they could hold a job. Once all such programs stop supporting their lazy ways they get a job and prove they can work.
There are a lot of people deserving if help because they are unable to help themselves. However I have personally known a number who are pretending to need help so they can be lazy. Telling the difference is easy in practice, but hard to write down formally.
