Option E is to run healthcare entirely as a business. Payment up front, and refusal to treat anyone without payment.
Option S is to take option E, but avoid immediately attributable deaths. Treat somebody at the emergency room, even if they don't have a line of credit with them. Patch them up enough to walk out the door, but don't treat the underlying issues without additional payment.
Option G is to treat patients before they reach death's door, when it is cheaper to do so. To give the preventative care that keeps costs down, even if somebody isn't able to pay for it. To treat public health as a public good, rather than as a series of purchases.
Option E is evil, to let people die unnecessarily. Option S isn't openly evil, but is stupid. It is where the US is now, and inflates the costs tremendously. Option G is to actually be good.
