Economic Possibilities for our Grandchildren (1930) [pdf]
I think the two big problem with Keynes analysis are
1. He underestimated how much we wanted stuff vs leisure. We have much bigger homes now, eat more meat, have computers and television etc. 
2. He underestimated how much work had to get done that he didn&#x27;t count. He was from a class that had servants and of course all the invisible work done by women. Raising a child doesn&#x27;t take substantially less person hours today then it did when Keynes wrote this. Neither does cleaning, since we now expect everything to be cleaner.
