Answer: This is a very controversial topic but can be learned from. Donald J. Trump built the wall for protection around America. Many Mexican immigrants have been crossing illegally with no passport or identification. Many had one goal and that was to move to a better place where they are free with their families. Others had a goal, that was to smuggle illegal things into America for other American drug dealers and weapon dealers. It was a good move on the presidents part and saved us a whole lot of damage. Yes, it may have affected the Mexican immigrants but because of their actions this wall had to be put up. Now don't get me wrong there are many good well manured Mexican people and I have nothing against them. The wall was really meant for the people who wanted to do harm to America and had no right to be here.
