That seems like it lands in the distribution ballpark the comment above was referring to, yes. The poorest 10% not paying very much in taxes is a feature of the system. And assuming your figures are correct, that 71% might look like a lot until you consider that the marginal tax rate for the very rich is very, very low in the United States compared to other developed countries, or even the United States prior to the Reagan administration.
