How does the U.S harm Mexico? How does Mexico harm the U.S?

Mexico and the United States, both very different countries separated by a wall known as the border. Because these two countries are so close they both affect each other. Sadly, it's not always in a positive way. Mexico and the United States both harm each other in many different ways. For instance, illegal immigration. This affects the United States negatively because the illegal immigrants get jobs, free education and alot of things that U.S citizens would normally end up paying for. Also, Mexicans have smuggled illegal weapons, drugs and even people over the border. The United States has also caused Mexico harm. The United States has a tendency to discriminate those who have crossed the border, whether legal or illegal. There have been cases where Mexicans who were here legally were not able to get a job due to the racism of job owners. Also, the United States pollutes a lot. Because Mexico is so close, they get a lot of the pollution we make. Therefore making Mexico suffer from pollution of water and air. Not only that but the United States makes it hard for mexicans to cross the border legally. There's so much paperwork you need to get done and some people just don't have enough money.
