“Even if you take a pure market view then there is some discoverable optimal level of immigration that would exist in a totally privatized society.”
And that “optimal level” is not a fixed level. It changes whenever someone has a lawn to be mowed and not have any US national takers to do the job, and whenever someone has a house to rent and not having a US national willing to take the price. The “optimal level” is just like any optimal price level in a free market, to be discovered and re-discovered every minute of the day, not some bureacratic quota.
“With the rampant government violation of property rights, nationalization of land, and the offerring of incentives to illegals in the form of government services, by definition we’re going to be dealing with way more immigration than we otherwise would be in an ideal world.”
Not true at all. For the first time in a long time, in the past year, more US nationals emigrated to Canada than Canadians emigrated to the US. I went to an American (US national) enclave in Mexico on a business trip early this year, the real estate price there is already rapidly approaching US prices (as in coastal US prices, much higher than the middle parts of the US), all bid up by US nationals who are considering retirement there. Let’s face it, red tapes and taxes are not attractive to either native borns or would be immigrants.
"But then that’s the difference between theory and practice. "
Of course. I’m not sure why I should feel guilty about using public roads: if I could put the money levied from me as gasoline tax instead towards private turn-pike companies, I’d probably be driving on much better roads . . . I’m simply being coerced to use public roads. The theory of anti-immigration is that if we crack down hard enough on immigration, it will stop, and the crackdown doesn’t cost us much . . . it’s as silly a theory as one propose that if we set speed limit on highways to 40mph, nobody would be driving quicker than that; if we set up roadblocks every few blocks to check driver’s license, we’d have a much better economy because we woudn’t have unlicensed drivers. It’s patent nonsense because the draconian measures will have enormous economic cost, both in terms of new bureacrats that would have to be hired to do the enforcement and lost opportunity costs as people are stuck in non-moving traffic or slow moving traffic. In the case of immigration, the anti-immigration theory won’t work at all. People won’t stop coming (and going) just because it’s illegal. In practice, the anti-immigration policy would only lead to:
(1) higher taxes to pay enforcement, both for hiring new bureacrats and for government contracts to set up high-tech and nearly useless barriers;
(2) impairment of private capital: (a) the barriers will have eminent domain issues; (b) nominal wages will go up, imparing savings; btw, real wages will not go up, just like minimum wage laws banning a different class of workers (those with productivity below a certain threshold); (c) business owners and real estate owners will have less counter parties in their trade
(3) severe civil liberty risk to US nationals: all the tools that can be dreamed up to control population flow can be easily adapted to use against the next population group that gets declared “illegal.” Historically, walls always served the dual purpose of keeping the population inside in and keeping those outside out; usually more the former than the latter.
On top of these three practical downside, there is an even bigger one for those who are interested in advancing liberty within the current political framework:
(4) Anti-immigration cost elections. Apparently, there are enough legal immigrants who have experienced what a mess the law is in that regard, and enough friends and relatives of “those people,” and enough business and individuals that realize at least one of the three facets enumerated above, that there is at least a silent majority who are against politicians who embrace it. Just look at Tancredo, despite the shrill voice of some of his ardent supporters, his campaign went nowhere. Republicans already lost the last congressional election because of anti-immigration sabre rattling.
