We must fix all of the problems not just the symptoms.
The root cause of undocumented workers is that American businesses PAY them to come here. We must enforce the border, pay living wages to farm and meat processing workers and fix the guest worker program so workers can move farm to farm.We should adjust tariffs and trade agreements on imported foods so that US. farms can compete with foreign imports.
We need to enforce the laws on employers to prevent more undocumented workers and deal with the generations of undocumented families here now who are law abiding, by offering a choice if they are not convicted of serious crimes: a) stay here with a permanent green card (not allowed to vote) or (b) go back and get in line to immigrate legally.
