This guy is completely full of shit. Capitalism is not a political system, as stated in the definition he provides in the beginning; I don't know where he got it, but here's the definition in the free dictionary:
http://www.thefreedictionary.com/capitalismcap·i·tal·ism (kăp′ĭ-tl-ĭz′əm)
n.
An economic system in which the means of production and distribution are privately or corporately owned and development occurs through the accumulation and reinvestment of profits gained in a free market.
And another
http://dictionary.reference.com/browse/capitalism?s=tnoun
1.
an economic system in which investment in and ownership of the means of production, distribution, and exchange of wealth is made and maintained chiefly by private individuals or corporations, especially as contrasted to cooperatively or state-owned means of wealth.
Wikipedia:
https://en.wikipedia.org/wiki/CapitalismCapitalism is an economic system and a mode of production in which trade, industries, and the means of production are largely or entirely privately owned.
None of the definitions here say anything about politics either:
https://www.wordnik.com/words/capitalismWhere does Paul get the idea that capitalism has ANYTHING to do with politics? AFAICT not even Marx called capitalism a political system.
Combine this with the fact that Paul founded a corporation--a public entity, at least partially--and runs a hedge fund, and dares call the freakshow of the last few decades "capitalism", it's pretty obvious that he's got malintent and wants only to confuse and divide the public, which does very well for the wealthy to continue their horseshit while people try to get their shit together. What an evil piece of fucking ass. And fuck TED for allowing this to occur at all. "Rethink capitalism," yeah he's rethinking capitalism all right, to whatever he claims capitalism to be.
