Who wants to do all that? We should build a wall because we are a sovereign nation that has the right to say who enters and how they enter. We should build a wall because we are deeply in debt and millions are wanting to take advantage of programs we can barely afford. We should build a wall because there are people who want to come in with the intent of hurting people, whether common criminal or terrorist.well theres lots of things you can do to improve peoples standards of living before you first: build a wall and second: kill all the jews i mean muslims i mean terrorists.
