The point is that this doesn't just discriminate against those relying on state benefits (or "rights", as I'd prefer to call them). It discriminates against those who might possibly, in the opinion of someone following an agenda, in the future rely on state benefits. So basically anyone and everyone whose face doesn't fit the right profile.
This is Trump's America entering the dystopian future of "pre-crime", where you are punished for "crimes" you haven't committed (yet). Except they're not using the futuristic science of Philip K Dick's Minority Report. They're just using plain, old-fashioned racism.
