How does Ford inadvertently assist Rockefeller and JP Morgan?

Ford inadvertently assists Rockefeller and JP Morgan through the establishment of Standard Oil gasoline stations. As Ford popularized the automobile with the introduction of the Model T, the demand for gasoline surged dramatically. This created a burgeoning network of gasoline distribution necessary for the increasing number of cars on the road.

Standard Oil, under Rockefeller, was already a dominant force in the oil industry, and the proliferation of gasoline stations became crucial for their distribution strategy. By increasing the accessibility of gasoline for Ford's consumers, Ford’s success in the automotive industry fundamentally supported the infrastructure that Standard Oil was expanding. Thus, without directly intending to do so, Ford played a significant role in facilitating the growth and sustenance of Rockefeller's oil empire.

The other options do not accurately capture Ford's unintentional assistance to these industrialists. Promoting electric cars would not have helped Rockefeller, as he thrived on the oil business. Manufacturing cars using exclusive parts would imply a partnership that doesn't reflect the uncontrolled support Ford provided to Rockefeller's established market. Investing in competition would counteract the interests of both Rockefeller and JP Morgan, who were more profitable when Ford's innovations heightened the demand for their services.
