Border walls don’t make it tougher to get in. They make it tougher to get out. Non-documented immigration happens in cycles where people come to our country to earn money and then return to Mexico. If we build a wall they will have no choice but to stay and avoid being incarcerated. Real change isn’t going to happen until Mexico strengthens its economy which will provide incentive for its citizens to stay because they won’t need to leave to provide for their families.
