What purpose will it serve to amend the Constitution with a provision that the government won't enforce? We have laws in place that are essentially being ignored, or least not being enforced. Start enforcing existing laws and deporting illegal aliens.
One change in law that would be constructive would be not to confer citizenship on children of illegal immigrants born within our borders.
"One change in law that would be constructive would be not to confer citizenship on children of illegal immigrants born within our borders."
Now that should be a constitutional amendment we push. Something like
'Any person born in the United States whose parents were not both legally American citizens is not an American citizen and has none of the rights American citizens have. Any person not an American citizen, though residing in America legally, generally has the same rights American citizens have under law, but regardless of those rights may be deported upon Executive decision, without recourse to law.'
It really doesn't matter what laws we pass, though, because as you mention the government ain't enforcing them where they matter most. Still, passing that amendment would be much more likely to effect a change in America's ability to keep illegals out and kick them out.
