For the US healthcare system you can add poor people without insurance using emergency rooms as their primary point of care. Emergency rooms are required to treat them, they can't pay, so those costs get shifted to other people. Worse, the care they receive is usually the bare minimum and there's a good chance they end up back there. Overall a horrifically inefficient way to socialize medical costs.
