Mexico is incredibly violent and corrupt. It’s no wonder so many Mexicans want to come here. But….eventually blame must be placed fairly.
This is only one story, but in conjunction with hundreds of similar ones, the only conclusion with explanatory power is that what is wrong with Mexico is that it’s full of Mexicans. What fraction of an area’s population has to be Mexican before it reproduces Mexico’s pathology is, unfortunately, being answered empirically here.
The obvious objection is that individual Mexicans are fine and it’s the system that is corrupt, and the system should be reformed so that everything will be OK. I am sympathetic to that objection. However, as a professional statistician, I have a finely developed sense of when there is enough data to draw a conclusion. Mexico has been this way for too many centuries, through too many reforms and elections and revolutions. It may be true that there are several distinct kinds of bad Mexicans (corrupt oligarchs, ultraviolent druglords, pitiless hate-obsessed revolutionaries) but the point is that ordinary typical Mexicans tolerate and enable the bad ones and always have.
The presence of the USA as a “safety valve” may have hindered reform because reform is difficult and, in a corrupt society, dangerous: most reformers (and, eventually, revolutionaries) are reluctant participants who have nowhere else to go. All the more reason to send the Mexicans back home; although most Americans realize this, this is one of the two issues on which the opinions of ordinary Americans carry almost no political weight.
This is because there are very strong influences in both major parties to continue to allow uncontrolled Mexican immigration (and the problem IS Mexican, not broader, they are 2/3 of the illegal immigrants and an even larger fraction of the unemployed or criminal illegal immigrants). The Democrats are importing a new population to outvote the white citizens who inconveniently prefer Republicans; the Republicans are either influenced by business interests that want cheap labor, or blinded by myths about America being a nation of immigrants that ignore the importance of where the immigrants are from.
By the way, the other issue on which the opinions of ordinary Americans carry almost no political weight was the subject of my previous post; it is even more mysterious to me than the illegal immigration issue, because for immigration I have just explained why the parties don’t listen to the voters, while I can’t explain why voters rejecting gay marriage in direct ballot questions in 31 out of 31 states seem unable to stop its political progress.
