No, I mean that the eligibility is not present.
Getting employment requires hurdles many people cannot pass: you need a registered address to get postal letters (which excludes many homeless), you need valid immigration credentials, you need skill certifications (school or academic degrees, vocational training, ...) for many employments (which foreigners sometimes have a hard time showing (refugees) or getting recognized legally), you need to speak the language, you need to be able to read and write...
For us tech people, a lot of these hurdles don't apply, but the lowest rungs of employment / society have a very difficult time which most of us don't have any experience.
