This whole-item context. For an insight into the truth of that headline-quote observation, follow the link in the post below this one. For more context on that linked item in the prior post, look here, scrolling to the Magerman quote for the gist, then scan the entire thing. Perhaps wrong, I see robber barons and politician purchasers as having negative social value. I doubt that's a wrong view, however. I see Mr. Mercer and daughter as a disease.
In fairness, "disease" might be too harsh or precise a judgment, make it "some form of pathology." The added ambiguity does not hurt the thrust of the thought.
Robert and Rebekah Mercer are heartless thugs, with money. If social, moral conscience were to be the measure each merits life in prison without parole.
Do read that Globe and Mail item. It is short, clear, and sobering. Thugs at work rigging both sides of the health provision/consumption equation. Thugs like the Mercers. Like the UnitedHealth CEO and/or its board chairman. Any Senator or Representative not 100% behind single payer should be replaced. A better system than "Slime Prospers" is needed, but don't wait for the new Trump communications coordinator to say so. He prospers.
