why build a wall then?
the only reason i can see to build one is because illegals commit more crime than whites. i dont see the job stealing as a reason cause we can just enforce making employers check citizen status, and drugs are too easy to find alternative ways to get them in here or they could invest a fraction on drug scanners, i think i heard a hundred million would help with the eighty percent of drugs that come through legal ports of entry.
if you are being consistent it's either a wall and limiting immigration based on skin color, or no wall and not limiting based on skin color.
or, why build a wall then?
