From WaPo article purportedly debunking health insurance lies:
"Private insurers have effectively engaged in rationing, so they're doing the dirty work for everybody else," said Jeff D. Emerson, a former health plan chief executive. "It's a thankless job . . . but somebody has to do it or health care will be even more expensive than it is now."
Private insurers might be better situated than the government to do the unpopular work of saying no, said Paul B. Ginsburg, president of the Center for Studying Health System Change, because they are less susceptible to political pressure.
There you have it. For-profit companies best serve the public interest precisely because they are not subject to public control. Why? Because the public wants what is worst for the public. And how does the Washington Post know this? It has dinner with all the right people, and charges them for the privilege.
