Antitrust laws are called antitrust for a reason.

The U.S. government made a great move in protecting the interests of its citizens a couple of weeks ago when it announced that it filed antitrust suit against AT&T's intent to acquire rival company T-Mobile. This suit puts a block on a merger that would have been disastrous for the United States cell phone service market. Had this deal have gone through, American cell phone subscribers would have their scanty selection of four major carriers reduced to just three. By reducing the number of carriers, competition is reduced along with innovation. The remaining companies would be even more content in the shared monopoly that they hold and would have no need to aggressively compete in order to attract customers. Some argue that we should just let capitalism run its course and allow these companies to do whatever they wish, but I argue that cell phone service is no longer a luxury but is now practically a necessity.  The government, therefore, has a duty to protect its citizens from price gouging, and it is doing a great job at it, as is evident by the antitrust suit directed at AT&T.
