Looking at the latest, depressing new addition to the U.S.-Mexico border (bought with your tax dollars at the bargain rate of $1.2 Billion and racking up maintenance costs of $8.3 million PER MILE, PER YEAR) a few more famous border walls come to mind . . . the Berlin wall, Jerusalem and the North Korea-South Korea border.  Think about the ignorance and hate that built those walls.  Do we really hate our Mexican neighbors that much?  This is out of control.
