Unfortunately for all involved, the poor are people too and to decide to make their lives as uncomfortable as possible in order to force them to get a job is maybe logical but certainly not a kindhearted thing to do.

Furthermore, it is likely that in many cases the very poor don't work because they are unable to -- mental illness is a commonly cited factor, but these days it's hard for anyone to get work -- particularly those lacking high school degrees, for instance. If someone cannot work for such a reason, then by attempting to punish them for not working you simply reduce their already-slim ability to contribute to society.
