How Mexico Helps The US And How It Harms the US

Mexico helps the U.S. by having immigrants (Illegal or not) taking the jobs of the people in the U.S. that they would normally not want. Unfortunately...that is all I can think of on how Mexico helps the U.S. But how Mexico harms the U.S., Mexico is constantly sending their waste and sewage into our oceans polluting the U.S. even more. Mexico also has many illegal immigrants both breaking laws and overpopulating our cities.
