To me as well the article seems disappointing. Is not-quite-explicitly-stated assumption that most of those in the 20% income were entitled to it without doing much work is wrong. The author keeps pointing to politicians as examples of those at the top (likely because most people do not view them favorably) and ignores professionals, business owners, etc. who often built their way there without starting in the top 20%. And the solution? "You, in the upper middle class, feel guilty!". Ouch!
