The business model of the largest companies by 1929 was notable for its ability to control a substantial portion of U.S. wealth. During this period, a number of corporations, particularly in sectors such as oil, steel, and finance, amassed significant economic power and influence. This consolidation of wealth was largely the result of practices such as monopolies, mergers, and acquisitions, which enabled these companies to dominate their respective markets. As a consequence, they not only influenced economic trends but also impacted political decisions and social policies of the time.

This consolidation of wealth also reflects a broader trend in the U.S. economy during the 1920s, as industrialization and the rise of consumer culture created a landscape where a select few corporations were able to retain vast resources. These companies often had the capital to invest in technology and marketing, furthering their control of the market and shaping the economic environment of the era.

The other factors—government control, competition from small businesses, and a focus on agriculture—did not accurately capture the economic dynamics that characterized the largest companies of this time period. The telecommunications, automotive, and retail sectors also experienced growth but were largely influenced by the dominant corporations, which overshadowed smaller entities and players in the market.
