WSJ: wealthy have more, pay less proportionately in taxes since 1929. Anybody surprised?

See this TaxProf posting with an excerpt from the Wall Street Journal article by Jesse Drucker, Richest Americans See Their Income Share Grow.  The tax rates for the wealthy are down, really down.  Their incomes are up, really up.  (And that's just AGI, which doesn't capture everything by any means.)  And the amount they are paying in taxes as a proportion of their incomes is low, really low.  That's bad for the vast majority of ordinary Americans whose incomes have stagnated and whose expenses make it more difficult than ever to live a decent life. 

Republicans in Congress, wake up.  There simply are not enough people in the top 1% to vote you into office.  You need to pay attention to ordinary people--i.e., at least the 80% who are not in the top quintile of the income distribution--and quit talking about estate tax repeal, capital gains tax repeal, and all those other goodies for the ultra rich.  The life of our country depends on it.
