Bernanke is a sly fox.
He talked a lot of richness,
richer-country->more services->better wealth and so on,
but he refused to speak about inequality.
USA is as unequal as many african countries,
have very high incarceration rate and so on (and it is not the richest country in per capita terms - Norway is richer).
Well, inequality creates concentration of power in the hands of a small group of people, creates feeling of unfairness in society ("the rigged towards rich fat cats"), increase overall stress on people. Did mr Bernanke ask regular folks - bus drivers, sales clerks, janitors - are they happy? or happier that 40 years ago?
Do you know that people of former GDR, well 56 % of them say that they want wall back??? Even though it was a quite poor country compared to West Germany???
