I am not really certain about the helping role of government in the film. Coppola's film really presents the idea that government is in collusion with big business to squeeze out the competition. In the film, "the Big Three" are able to enlist the support of a Michigan Senator in order to pressure Tucker and use the force of the government against he and his efforts. It is government whose pressure is brought to bear on Tucker and is what ends up causing him a great deal of challenge. I am not entirely certain that this level of government intervention even hoped to provide some level of help to Tucker. The "Big Three" did a good job of working with government to crush the small business that Tucker had in competition with them. In this light, the federal government is more of a servant of capitalism than its master.
