It's official: America's middle class now earns less money for more hours of work

One crucial factor left out of the NY Times story "The American Middle Class Is No Longer the World’s Richest" -- that would mean American income inequality is even worse (if you can believe it) -- is that Americans work longer hours than Europeans or Canadians too (probably more family members work those hours for more years).  

Now, if the per capita income of our middle class (defined as median income) is barely equal to or lower than that of other modern middle classes -- and --  we work more hours to get less ...

... Holy Cow; it's time for some very big changes!
