At least if we're talking about the US (and probably EU as well), it isn't the choice between life and death. Anyone can go be homeless in California and get a couple hundred a month in food stamps and medicaid. Or panhandle a few hundred a month from tourists.

I agree you shouldn't literally die if you choose not to work in a first world country, but you should only receive the bare minimum to keep you alive (e.g. a tent, basic medical treatment and a steady diet of government cheese).
