Besides Rockefeller's direct competition, who else suffers due to his business strategies?

Rockefeller's business strategies, particularly his ruthless tactics to eliminate competition, had significant consequences for workers in various ways. As he sought to consolidate his control over the oil industry, many smaller oil companies were driven out of business. This consolidation often led to job losses as these companies closed down or merged, resulting in a reduction of job opportunities in the oil fields and refineries.

Additionally, Rockefeller's practices often involved lowering wages for workers to maximize profits. In his quest for efficiency and cost-cutting, labor conditions could deteriorate, leading to long hours, demanding work conditions, and minimal pay for those who remained employed within his companies. This focus on profit and control came at the expense of the workers' rights and well-being, illustrating the broader impact of business strategies on labor.

Considering the other groups mentioned, while investors and shareholders might experience shifts in profitability and the value of their investments as companies shift in the competitive landscape, their overall strategic interests were often safeguarded by the strong market position created by Rockefeller's consolidation. Consumers, while facing potential price fluctuations, can also benefit from lower prices due to economies of scale achieved by such monopolies. However, workers directly bore the brunt of the negative consequences stemming from Rockefeller's aggressive business approaches.
