Governments-States have many responsibilities including in modern times: maintaining the integrity of the geographical area, ensuring transportation and communication, controlling communicable diseases and in the case of the wealthier states providing for the general education and welfare. However, the first and most basic function is protecting citizens from violence. States that cannot do that are Failed States. Mexico is now entering that world. 2017 was its most violent year since regular data collection began and 2018 is more violent. Mexico has 130 million people but now every state has high levels of violence. Two of the most violent are states on the border with Texas: Tamaulipas which reaches from Laredo to Brownsville and Chihuahua that has one major Texas city as a border city: El Paso.

Here is the road at the border into one of the Mexican cities: And the city proper: But one of its neighborhoods is less appealing: 

This neighborhood is far too typical in much of Mexico. Average daily wages are $10.00. Average educational level is the 7th grade. Both Central Americans where life is even more harsh and now Mexicans are seeking to leave and head north in record numbers! Recorded legal and illegal immigration is about 1.5 million each year. I expect it to rise.
