Love the way you reversed the point, lololol!
You do NOT need a wall with the Atlantic or Pacific ocean, because millions aren't walking on water trying to get in!
You do NOT need a wall with Canada for exactly the same reason.
You DO need a wall with Mexico, because not only are their citizens trying to walk across, almost every country below them are sending their people through Mexico to cross also!
And, as a side note---------->you can NOT as a government make a tax policy for economic growth for your citizens, if every damn time your policies create 2 or 4, or 6 million jobs for your citizens, only to discover that you need 2, or 4, or 6 million MORE jobs because that many people have crossed the border and are now added to the amount of jobs you need. What in the hell is the point of American taxpayers giving breaks to business to hire our people, only to discover 1/2 the jobs are taken by people weren't even here before, and the other 1/2 need a handout to live raising taxes even higher!
Not a one of us mind if YOU and YOUR friends want to contribute cash to the other side of the border. As for the rest of us, you do YOU and leave us alone!
