We are having a torrent of business mergers nowadays. It is facilitated by free money and free money mainly benefits the large corporations. When companies merge, they appeal to the Trust regulators on the basis of world-wide competition. But, invariably, a large percentage of their business is done in America. Yet, it is a fallacy to look at a merger on the basis of day to day competition. Concentration of the economy has far more implications, as well as serious consequences.
There was a time when Congress was concerned about this type behavior, but that was a bygone time and place.
