I'm not getting into a political arguement here, but they suck. They may keep people from becoming unemployed since most immigrants would be willing to be payed less than minimum wage to get just any job, but what about the families that are torn apart because their family member/s is/are not allowed to cross the border? Or what about the medicine and medical procedures that are not given in some countries? Or the deprivation of clean water and warm food? A roof to sleep under? I don't think it is fair. Illegal immigrants I can understand, but their families must be thought about. Allow those who don't qualify for a green card to allow their family members access and a certain amount of days to be with their loved ones. Send those in need a care package with food, water, clothes, and money. Send what you think you would need in their situation. They are just trying to get out of harsh living conditions. Think of what they must have gone through. They want freedom and a better life than they had. Give them a chance. Don't just "build a wall" because you're narrow-minded and turning his/her head to another's struggles.
