Paul Tudor Jones (PTJ) is a legendary trader that runs one of the largest Hedge Funds in the world....Tudor Investment Corporation. He recently gave a TED talk about income inequality. https://www.youtube.com/watch?v=vesdt5vDIek PTJ shows data documenting a 40 year high in corporate profits as a % of Revenue and a 40 year low in the percentage going to labor (Classic substitution of capital for labor). I guess todays corporate leadership doesn't think like Henry Ford who famously paid his employees enough to ensure they could buy a Ford Automobile.
PJT has created an independent non-profit organization that will poll 20k Americans annually to define corporate societal responsibilities that they will use to rank the largest 1000 US companies.
Interesting that the early comments on YouTube are mostly negative. Commentators seem unconvinced PTJ is genuine. PTJ concludes that historically this level of inequality ALWAYS is corrected via Taxes, Revolutions or War. So is he worried about "killing the rich people"? Perhaps, but someone of his stature needs to quit the BS that optimizing shareholder value is Smith's invisible hand. Read Smith, it's not.
I've been inside the core of the Technology business (semiconductors and software) for over 35 years. I see four changes that are creating winner-take-all monopolies by compounding capital much faster than when I started in the 70's...
1) Repeal of Glass-Steagal and conversion from LLC's to Public Companies driving TBTF Banking the largest corporate sector in total capital and profits. We have ~$800T in capital supported by a ~$80T global economy.
2) Knowledge (IP) , when exchanged, creates 2 owners of the same IP. The knowledge economy is a mathematical engine for exponential growth. Most of world economic history was built upon physical object transactions which does not implicitly create shared ownership.
3) Globalization especially w/respect to the benefits of 2)
4) The flawed assumption of Ergodicity in economic teaching and policy now well documented as a mathematical error in Menger's foundational book that created "modern" economics, http://rsta.royalsocietypublishing.org/content/369/1956/4913 . Lucky money compounds to +infinity but unlucky money stops at zero... game over for the unlucky.
I believe these have created a tangibly different environment than our economic history books. I agree with PTJ that unintended consequences (inequitable distributions) will not settle out before Capitalism's benefits fail to benefit the majority of the people.
