I wanted to point out that while the Meades of the world love to yell about that "fifty eight percent!" statistic, they are not nearly as vocal about the total yearly income of the ultra rich, nor is it at all easy to find since they so love to bury their real incomes inside of legal constructs that have become so complicated it's impossible to trace the money movement.
In other words, Meade doesn't want to discuss the ways people like Mitt Romney can game the tax system (though he won't let us see how he did it) and wind up paying a relatively low tax rate, but his father George Romney not only paid his taxes (as shown by the dozen years' worth of tax forms he released to the public) but actually did not take advantage of a number of loopholes because he believed it was his civic responsibility as a wealthy person to generously support his country's government.
That's off limits. We can only talk about that certain itty-bitty, carefully-defined subset of an individual's overall economic activity, assets, and life that shows up on their 1040 as "adjusted gross income." Nothing else.
