Yes this is true. Far from enough to say that because of this we have socialist goverments though and too close to what free market is anyway because what you described doesn't change the fact that the market will not grab the profit that can be grabed and be selfregulated. The mechanisms are the same. Similarly, we never had a classless society, thus we never had true communism. Is there an indicator that there could be a selfextingt nomenclature? No. Just like there is no indicator that markets can be selfregulated if we can print our own money etc. Instead we have proof that if we leave markets unattended, disaster will follow.
