Original sentence: In the United States, the lack of metro, subway, or rapid transit systems except in a few of the larger cities has been attributed to the influence of the  automotive industry and oil refining companies, which essentially used automobiles, buses, and advocacy of public road-funding to compete effectively against existing streetcar and trolley systems, which went into decline early in the 20th century as the public chose personal over public transportation
Edited sentence: In a move some cite as direct corruption and manipulation of power, the Big 3 bought and shut down the only existing trolley public transportation that was supposed to become a full Metro.Many people cite the lack of a Detroit Metro to be the fault of the extreme power of the “Big 3” or Detroit based Auto Companies of Ford, Chrysler, and General Motors.Many say the Detroit want to become a “car only” non-public transit city to aid the Big 3 fueled this idea.The Detroit area politics has long been run by money from these companies (sometimes behind the scenes)
