It reminds me of the arguments that communism must be a good idea because we haven't seen true communism yet. We've seen true capitalism for much longer and much more clearly than we've ever seen any form of communism, and it's exactly what the US has. You can't just hope that maybe with a little more regulation, or a little less regulation, or something, capitalism will magically work. Capitalism sets up incentives for people to figure out regulatory capture and lobbying in whatever regime you come up with. Capitalism sets up incentives for companies to influence the public to believe that certain forms of government intervention are perfectly natural (take copyright, for instance - if you convince everyone to get rid of copyright, you'll just set up incentives for companies to convince everyone to bring it back). If you think this isn't working right, please work with the folks who want to figure out an alternative.
