Re-read an article by Chris Dixon (VC investor) about being a "builder" versus an "extractor" -- creating more value for others vs capturing more for oneself. In it, he specifically called out Wall Street as being on the value capture extreme.
What do you think of this view? Does Wall Street create more value than it captures?
(Note: I don't think he's saying that builders do not extract value, nor that extractors do not create value, rather what is the net effect. Source )
