I think you have a good point, but I don't see any changing quartile analysis or percentile analysis of income distribution. I did find this: http://www.aei-id

I think you have a good point, but I don't see any changing quartile analysis or percentile analysis of income distribution. I did find this: http://www.aei-ideas.org/2013/07/yes-the-middle-class-has-been-disappearing-but-they-havent-fallen-into-the-lower-class-theyve-risen-into-the-upper-class/ http://www.aei-ideas.org/2013/07/yes-the-middle-class-has-be... but it seems to fail to account for the fact that overtime, more and more households have become two working person households. IDK, I just haven't seen a clear and compelling analysis that says that we are heading toward winner takes all.
