You don't need perfection. If you ARE demanding perfection, then you're the one living in a dream world.
Big deal. As soon as they lose or quit their job, they move. Then try finding them.
They'd have to abandon things such as their cars.
And they'd have to have a perfect police record. ANY arrest would equal deportation.
And in the situation where it's relatively easy to hire a legal worker compared to now, fewer businessmen will take the chance of doing so. This will make finding the ones that do much easier, as their anomalous behavior will stand out against the background.
Illegals drive around without liscenses or insurance right now. What makes you think ti will be any different?
And they'd have to have a perfect police record. ANY arrest would equal deportation.
We don't deport the illegals we arrest right now. What makes you think that's going to change?
And in the situation where it's relatively easy to hire a legal worker compared to now,
It's not hard to hire legal workers now. You just have to pay them more than illegals. Plus if you pay them in cash, like a good chunk of illegals get paid, you don't have to pay unemployment insurance or FICA. You can even pay them below minimum wage. The same will be true after the amnesty is passed, and unscrupulous employers willing to save a buck by hiring an illegal today will be just as willing later.
The only provision that's going to ever work in keeping out illegals, whether or not you pass an amnesty, is mandatory employer verification of legal status and strict enforcement of that provision. But if you pass such a law, you don't need to give any amnesties or deportations. Without jobs, they'll leave. Problem solved.
