Out-of-control healthcare spending is the only stimulus the Republicans can't stop. What else is there? Go out late at night in some of the darkest American cities. Whether it's Cleveland, Baltimore or St. Louis, it seems the only thing left to light up the gloom is a big hospital, shining like a 12-gated city, inlaid with MRIs like precious jewels. And for that we can give thanks to Medicare and Medicaid. Imagine Cleveland without the Cleveland Clinic, or Baltimore without Johns Hopkins. Even in Chicago, with a more diversified base, the city would seem flat without the expansion at Northwestern Memorial Hospital and Rush University Medical Center—with all that hammering and sawing as they get ready for Obamacare.
