Analyze and criticize this statement: 

The strategy of the Sherman Anti-Trust Act and other U.S. anti-monopoly legislation is to ensure that each company has meaningful competitors in every product market in which it participates. This strategy works to prevent monopoly pricing of products but, unfortunately, it is inadequate to prevent the development of quasi-political control of entire societies by oligopolies whose member corporations share a quasi-political agenda. Therefore, as the world becomes a single market, some new strategy must be developed to control the reach of the corporate oligopolies.
