No. may I say: that's a bad idea. We want a QUALITY wall built by those who are properly skilled and have an interest in seeing it built and operated correctly - NOT by those whom it will be used against, who will do what they can to ruin it. All the illegals may be capable of doing without suspicion of sabotage would be shoveling dirt.
Well, they could be forced to do those menial "jobs Americans won't do."
