Because I'm a bit of an odd guy, I have an abiding interest in differential pricing: How the poor pay more for the same products than the rich, how the uninsured pay more for the same care than the insured, and so on. Now I can add how the median limo-lover pays less for the same kickin' ride than the betrothed. Granted, this is a less pressing problem for social policy wonks than the other two, but still: Where's the outrage!?
