When I was a kid the border was more or less open, a question or two and "have a nice day". EZ crossings. The problem is NOT us, the problem is the Mexican government and the Mexican economy. I was talking to a guy (In Mexico) a year ago and he had been in New York a couple of years. I asked why he left and he said because Mexico is his country. It is the lousy economy in Mexico that is causing these folks to seek work in the US. Not really our fault.
I'd just as soon go back to an open border if the drugs disappeared and the worker influx stopped.
These days we are killing their economies to force them all to the US to topple her. Also today you are getting 2-3 mexicans out of 10 , the others are not mexican.
