I think you're probably too cynical, though it could certainly get as bad as you suggest. The problem is addressable even now -- a reasonably-effective guest worker program would probably do the trick: ensure that Americans hire only registered "guests" (which can be done via internet!); and make sure that the "guests" are taxed, through witholding.

Taxes will address many of the imposed costs; registration and tracking addresses the national security issues; and registration and witholding requirements address the financial incentives for businesses to hire illegals or guests.

But supposing you're right, and the problem cannot be fixed: wouldn't it make more sense to make the best of it?

wouldn't it make more sense to make the best of it?

It makes sense to at least try but it will be an uphill battle. So long as the "they pay taxes" and "they are only doing the jobs that Americans won't do" kind of crap is in all the MSM 24/7/365 then most American voters and the people they elect to represent them will never understand the problems well enough to actually do anything about it.
