If Trump, or anyone else, truly wanted to stop illegal immigration he will cut off the incentives for them coming here. That means no welfare, no schools, no medical and no employment. Period.
He didn't propose any of those things, which makes me think he's not serious. He's just saying "wall" because it gets everyone excited. If illegals had no prospects of benefits or jobs THEY WOULDN'T COME.
That right there is Wisdom.
You People.
