Peters points out that illegal immigration is a problem for places as different as South Africa and France, as well as the United States. He may be more sanguine about the future of the 12 million illegals now in the U.S. than I am, but he proposes what might be workable policy.
One of his recommendations I can heartily endorse:
What's the worst thing we could do about the new global migration? Ignore it. Postpone solutions. Pretend - as we did 20 years ago - that illegal immigration is a temporary phenomenon curable with a "one-time" amnesty.
