Final answer:
The change from multiple competing city bus companies to a single subsidized, regulated monopoly in major U.S. cities was driven by factors such as efficiency, regulation, and financial considerations.
Step-by-step explanation:
The change from multiple competing city bus companies to a single subsidized, regulated monopoly in major U.S. cities can be attributed to several factors. One of the main reasons is the desire for efficiency and coordination in public transportation. Having multiple bus companies caused issues such as overlapping routes, inconsistent schedules, and uneven service quality. The establishment of a single monopoly allows for better planning and management of the transportation system.
Another factor is the need for regulation and oversight. With multiple bus companies, there was a lack of uniform standards and safety measures. By implementing a regulated monopoly, the government can ensure that the transportation system meets certain criteria in terms of safety, performance, and affordability.
Lastly, the shift towards a subsidized monopoly is often driven by financial considerations. Maintaining multiple competing bus companies may not be financially sustainable, especially if they constantly undercut each other's prices to attract passengers. A single monopoly can benefit from economies of scale, allowing for cost savings and potentially lower fares for passengers.
