Its not going away... Corporations existed before fiat money, and they became predatory along with the money. They can be fixed. Bitcoin fixes the whole system 95% of the way - the last 5% is fixing laws.

yes, it is going away, if dark pools are now more of the "market" in "public" traded equities then the whole scheme is done for, because the volatility of supply now is more dark than visible... one big dark pool trade could completely change the supply dynamics of the bright side (public/retail/even moderately large corporations) in such a way as to lead to a dramatic rise in volatiility
the inevitable decline to decadence that always starts with one little "it's ok, you can eat one fruit"
