Ryan's returns reveal that he and his wife took in about 1/100th of what Romney showed on his tax return in 2010, but paid a higher rate--15.9% against 13.9%. But don't expect Ryan to complain about the apparent inequity.
(Although Ryan and his wife--almost half of the income came from investments, most in her name--received a tiny fraction of what the Romneys got in 2010, they are very close to the top tier of Americans in terms of their income.)
One more thing: Ryan turned over seven years' worth of returns to the Romney campaign. In other words, Mr. Romney thought it necessary for him to see much more information on his prospective running mate's taxes than he is willing for us, the voters, to see about his. Yet it is we who are making the decision about whether to employ the two gentlemen.
