If there was no reason to sneak into America would they stop? No hiring, no welfare, no schools , no anchor babies, etc., and it stops on its own!
Is that too simple?
Bingo! Now if we can get the cheap labor-loving, big business-loving Republicans and Democrats to agree, the invasion will stop. Clinton loved illegal immigration, Bush loves illegal immigration, and then there's the campaign debts to pay off..., so to hell with American workers and taxpayers. We're up against some big anti-American guns.
