"I'm going to build a great wall and Mexico is going to pay for it"-Donald Trump. The logical fallacy of oversimplification is when the solution to a problem is made to be very simplistic. Trump's concept of building a wall as solution to illegal immigration to the United States is a prime example of oversimplification. Trump is arguing that the solution that he is proposing will solve illegal immigration in the United States and that the Mexican government is going to pay for it. The sense of effortlessness that Trump portrays when talking about this plan shows that it is an oversimplification of a largely debated topic in American politics.
