Idaho observes:
"Why don't we just put them in chain gangs and put them to work on that wall."
Well, can't do that, but I have a better idea.
What I'd do, is make an offer to illegals already here -- many who do manual labor in the construction industry.
The offer:
Come work for us on the border wall.
We'll pay good wages, provide temporary housing and meals, etc.
Earn a certain number of credits for hours worked, and we'll grant you full and immediate American citizenship to both you and your immediate family.
How many do you think would show up ?
