What will we do in the future, as Americans, to reduce illegal immigration?

I just read an article that gave me new perspective on illegal immigration. A reporter stated “The responsibility for illegal immigration lies on both sides of the border; in Mexico, the lack of jobs and poverty that forces the Mexicans to enter America seeking employment, and in the U.S. the illegal hiring of illegal immigrants that encourages illegal immigration.” (Illegal Immigration – The people suffer while politicians squabble) While we cannot blame Mexicans for coming to America, we need to take more responsibility for what our businesses do. Even though our businesses are employing illegal aliens, it isn’t just our fault! Mexico has a low per capita income of about $4,000; therefore people want to immigrate to the United States to make money. Either way, I am not here to determine whose fault this is, but I am here to say that both countries have responsibilities in order to improve this situation. When it comes down to it, we want to welcome Mexicans into our country, but we need to require everyone to become citizens before taking residency. Most importantly, we do not need to upset Mexico because they provide us with large amounts of oil, car parts and electronics that we wouldn’t have otherwise. (Mexico's exports to the United States)
