Oil revenues constitute nearly 40% of the Federal government’s budget. After a decade of steady progress in poverty reduction, a severe production decrease will put public spending in jeopardy. In 2006, despite nearly identical sales of $100 billion, Pemex paid $54 billion in taxes compared to only about $36 billion by PDVSA, Venezuela’s state-controlled oil company.

In short, revenue from oil exports is the foundation of Mexico’s leap forward.
But, the specter of Mexico’s emerging public spending crisis looms on the horizon. Reality is quickly setting in. Second quarter profits dropped 56% this year over the same period in 2007. This decline in revenues has forced Mexican President Felipe Calderón to call for “an urgent reduction in public spending to reduce the enormous dependence on oil revenue.” It is no exaggeration to state that the government’s ability or inability to adapt to lower oil revenues will affect virtually every aspect of life in Mexico.

Given the country's obvious dependence on oil revenues, a projected sizeable drop in production is worrisome. Whether or not the new oil discoveries will ultimately offset the current decline remains to be seen.

Any significant shortfall in oil revenues, which leaves the government with less money to deal with domestic issues, will likely prompt more Mexicans to contemplate migrating north to the U.S.

• Net migration has "declined" in large part because we've ramped up deportations. Those count in the reverse column.
  
• I've already provided multiple links asserting their dwindling oil production is causing emigration.
  
• It is my extremely well-supported position that Mexico is among the many dozens of countries long past peak, yes. And no amount of privatized prayer and bending over for shale oil exploitation will make up for the decline.

Until recent years, most people caught illegally crossing the southern border were simply bused back into Mexico in what officials called "voluntary returns," but which critics derisively termed "catch and release." Those removals, which during the 1990s reached more 1 million a year, were not counted in Immigration and Customs Enforcement's deportation statistics.

Now, the vast majority of border crossers who are apprehended get fingerprinted and formally deported. The change began during the George W. Bush administration and accelerated under Obama.

They are down because U.S. job and housing construction markets are horrible, there's heightened border enforcement by nutjob cons, there's a rise in deportations, as well as all the other dangers associated with illegal border crossings. Are you aware that every Mexican sent home counts towards the stat your trying to champion? Probably not. But what does context matter in the mind of someone like you, who is akin to a RW climate denialist?
