My worry is that this problem in America—which is not really about medical debt, though I agree, medical treatment is absurdly expensive—is intractable because it's about inequality. The slogans of the Sanders campaign or OWS weren't about medical debt, they were about inequality. And a free society is, by definition, unequal, because status is a zero-sum game (and talents are unevenly distributed, and parental love means gains compound, and a thousand other effects). This is a problem because of a lot of self-esteem is tied up in status.
