The Mexican border state of Sonora, that is. From the Tuscon Sun:
A delegation of nine state legislators from Sonora was in Tucson on Tuesday to say Arizona’s new employer sanctions law will have a devastating effect on the Mexican state.
At a news conference, the legislators said Sonora - Arizona’s southern neighbor, made up of mostly small towns - cannot handle the demand for housing, jobs and schools it will face as illegal Mexican workers here return to their hometowns without jobs or money.
The law, which took effect Jan.1, punishes employers who knowingly hire individuals who don’t have valid legal documents to work in the United States. Penalties include suspension or loss of a business license…
…”How can they pass a law like this?” asked Mexican Rep. Leticia Amparano Gamez, who represents Nogales.
“There is not one person living in Sonora who does not have a friend or relative working in Arizona,” she said in Spanish.
“Mexico is not prepared for this, for the tremendous problems” it will face as more and more Mexicans working in Arizona and sending money to their families return to hometowns in Sonora without jobs, she said.
“We are one family, socially and economically,” she said of the people of Sonora and Arizona…
Family or not, Mexico has a problem. It could be called collectivism or socialism, but in Mexico’s case its most accurately called statism. The Mexican government consumes nearly half of the country’s economy (in the US its about 35.4%).
The Mexican economy should benefit from enormous structural advantages. 90% of its exports are to the US and Canada with almost no trade barriers. It is blessed with abundant natural resources - its the world’s 5th largest oil producer (right behind Iran). Their proximity to the US means they can get by with almost no military (the US spends 20% more on the Coast Guard than Mexico spends on its entire military).
A couple straightforward changes to Mexican law would help a lot. First, they need to dump their Expropiación Petrolera law. In 1932 Mexico nationalized (aka socialized) all foreign assets involved in oil exploration and extraction. It was good politics (domestically), but it has had a devastating impact on their petroleum industry. Pemex is run through a system of patronage and graft. There is no competition for natural resources, so the company is wasteful and inefficient - with side effects including environmental destruction and long term damage to reserves (by, for example, excessive injection of sea water). Opening the industry to foreign capital and competition would mean more exploration, more modern methods, more oil exports, and more domestic jobs for Mexicans.
The other thing they need to dump is Article 27 of their constitution. The Article stipulates that all land is property of the Mexican government, and that private property is a un privilegio creado por la nación. (”a privilege created by the nation” - ie not a right). This is a serious problem that reflects the country’s Continental legal heritage (as opposed to one derived from British common law). A more specific problem with Article 27 is the last sentence of Section I:
En una faja de cien kilómetros a lo largo de las fronteras y de cincuenta en las playas, por ningún motivo podrán los extranjeros adquirir el dominio directo sobre tierras y aguas.
Roughly, foreigners cannot under any circumstances own land within 100km of the border and 50km of the ocean.
One immediate impact of this law is obvious in this satellite photo of the area around Imperial Valley.

Can you guess where the border is?
What’s going on here - is the difference in agricultural development an issue of labor or capital? Well, since a good portion of the laborers on the north side of the border are Mexicans, its probably not a labor problem. Why the capital problem? Because the people owning and developing the land north of the border are legally barred from doing so on the other side. They look pretty crammed in to the valley up there - no doubt some would look south if they could. And with NAFTA their produce could easily be sold in the same markets.
Same thing goes for coastal development. How many thousands of Mexicans are employed building vacation homes for American baby boomers just a few hundred miles inside the US in places like Tuscon, or on the CA or FL coasts? Why don’t more Americans build retirement homes in places like Ensanada, or Playa del Amor, or Cancun? Because they effectively cannot.
Changing property ownership laws and privatizing (including international capital) Pemex would go a long way toward helping Mexico create more domestic jobs. Fewer of their hardest working, most ambitious citizens would working illegally inside the US and would instead be helping grow their own economy. Win-win.
But I think Hillary Clinton has probably the best solution for illegal immigration.
She’s already promised $800B in new annual federal spending (will take our government spending to >40% of GDP), she wants to nationalize parts of our petroleum industry, and she wants to slow our economic growth with increased taxes. She will simply make the US more like Mexico.
