I'm not really too educated on theory, but this seems disingenuous. Yes it has failed, and so has our current capitalism, ime.

I think in USA, we have a unique situation to give it another spin, and for it to be successful.

The only way to reign in the runaway greed train is to introduce some type of socialism, and that is a natural progression en route to "true" communism. Which, imo, is going to take a very long time, realistically.
