Many people become illegal immigrants by overstaying their visas. A wall's not going to change that. Also, the border isn't entirely land, so if the US built a wall across the Rio Grande, they'd be giving the whole river to Mexico.

stopping some illegal immigration and one form of it is better than doing nothing.  Just because it doesn't stop 100% of illegal immigration doesn't mean it's not going to help with the problem.  It's a deterrent like a dog at your house or a fence around it or padlocks.  People can still get past those things but they usually don't try as much if you have them.

But how has illegal immigration negatively affected the country?
