Well, depends. Do they say "open borders after we went the welfare state and entitlement programs" or "open borders right here and now" ?
First is understandable, even if I don't completely agree.
Second is elaborate suicide or apocalypse mongering. If so, I admit my mistake and apologize for my error, while horrified at such insanity and depravity.
Here & now. I usually riposte with Milton Friedman on the topic (can't have open borders with a welfare state) but that gets shrugged off. MF is insufficiently libertarian on this topic.
Check out the intelligence squared debate "Let Anyone Take a Job Anywhere."
http://intelligencesquaredus.org/debates/past-debates/item/909-let-anyone-take-a-job-anywhereBryan Caplan, econ prof at G Mason U, uses the debate to push for open borders, which is what the proposition would require. His sidekick is Vivek Wadhwa, who also is for it. He pushes the techno-libertarian open borders line. Both think it is a great idea,
not apocalypse-courting "lets bring down the whole system hahahahahah!" crazy talk.
Ron Unz and Kathleen Newland won (no to the proposition) pretty handily, mostly because though Unz is a geeky computer guy, he understands how to appeal to an audience (Manhattan).
I'm torn on amnestry
Against: for the same reasons mentioned above
For: well now they are going to have to pay income, FICA and Medicare taxes. Might be cheaper then trying to deport everyone.
The problem is that most of the illegals make little money and consume taxpayer-funded public services disproportionately.
The crazy fact is, in America you gotta make in excess of $40-$50k/year on average (and pay the full panoply of taxes on that income: sales, income, FICA, etc) to start
pulling the wagon instead of
being in the wagon. This is for ANY resident in the USA, legal or otherwise. Includes all the usual benefits one associates with welfare, plus the gov;t's legitimate activities like roads & such.
Given that illegals are disproportionately poor, most are pretty much in the wagon, not pulling ("pulling" meaning tax dollars paid > tax dollars consumed in gov't activity).
About 30% or more get on some sort of means-tested welfare once htey cross the Rio Grande. And they have greater birthrates in America than they do in Mexico. Because Americans subsidize their fecundity.
Deportation is relatively inexpensive, especially if you project out medicaid/medicare/social security costs. Also, it has been demonstrated that when the law is applied with vigor, illegals skeedattle. Seen recently in several states and back in the 1950s with Operation Wetback. Most self-deport once the heat is on. We could spend more on it by recording and using a "one dip and you're out" policy (one interaction with gov't: ER room, school, police, etc. and then back home).
