Hey, I also posted an article on Pikkety today: http://hubski.com/pub?id=147291
Also, I read an article on De Correspondent (Dutch journalistic site) about Pikkety a month ago and it featured this telling graph:
Red is return on capital, blue is the growth of the world economy. Notice the dip right after WW2, when lots of capital was destroyed or lost, and for the first time, capital (which Pikkety equals to wealth) dipped below the global economic growth. During that time of unusal economic equality, massive growth took place. One of his arguments is that a lot of our economic theories are based in that environment, which is historically an exception. Another argument is (I think) that equality has only decreased in the last decades and that it will continue to do so.
Interesting stuff nonetheless. Anyone here has read / will read his book? kleinbl00?
