I think there is a social value in not saying "you're poor and therefore your live is meaningless". Trading in human blood is something I find highly unethical.
Agreed. I also think there is a pathology in this country that presumes the way to address such moral yearnings is to order other people to do what we're too lazy to do ourselves. And that's what EMTALA does. It's what PPACA is all about.
To put it another way, if we think government should ensure that everyone has health care, then we should raise the funds legitimately, via taxation, and provide them with health care. I think it's wrong to simply turn to arbitrary mandates and demand that other people do things against their will to spare us from higher taxes.
We are actually in agreement on an extent, in that it would be better to tax and then direct address problems, instead of using regulations as a roundabout way to achieve the same end.
