It's also seems self-contradictory. Another bit of free-market dogma is the economy is so complicated no one can understand it, but if that's the case how can anyone tell that "goods and services represent tangible benefit to people, market prices represent the true value of goods in society, and wages represent the value that a worker provides to others" and not bullshit games, like the consulting described in the OP. I feel it just collapses into circular reasoning: "define what the market does as good and true, therefore what the market does is good and true."
