Adam Smith, a late 18th century economist, wrote about the importance of free markets and competition. He argued that competition kept prices low and quality high. Competition prevented monopolies and thwarted a business from becoming the only game in town. In today's modern economy, Smith would be surprised as there are few true free markets, the state plays a large role in the economy, and large multinationals dominate. Is the United States really a free market economy? As capitalism continues to chug away unfettered, is the end of history in sight? Karl Marx would say so, but not without the clashing of classes to move us forward into his version of communism: no more rich versus poor, no more classes to tussle.
