[Fear the Walking Dead] Why does Mexico seem so much better off than the USA in terms of maintaining a society in the apocalypse?

So, we see some undead in Mexico in FTWD, but... nothing compared to the destruction and infestation in America.

Is it because Mexico is more spread out? More arid, which might contribute to the dessication/decomposition of the undead?

Is it because the cartels have a metric fuck-ton of guns and no hesitancy to use them when "rioters" start feasting on the flesh of the living?

Mexico is very sparsely populated compared to the states. Outside of a handful of tourist cities and state capitols most of Mexico is about as densely populated as the US midwest. People are there but 40 minutes or more of driving between towns which is equivalent to a days worth of walking or more. 

The united states has several differences in consumer products as well that while not a major difference will provide Mexico a slightly better survival odds as supply chains are shorter and many goods like dry milk and non refrigerated food stuffs are more readily available in markets. This means people will be better fed and supplied even if the supply chain collapses unlike many regions in the USA where local production of food is impossible. 

But the largest difference between the USA and Mexico in the universe is the response of the public. The Americans were told to evacuate to large cities and protected by the military which unfortunately turned many more people than would have happened otherwise. This makes large cities in the US like turned over anthills spreading the walkers into the surrounding regions. Mexico by contrast is more spread out and the military controlled by much more powerful state governors who could direct them differently rather than following a nationwide mandate. Since their population was so spread out and unable to congregate as easily the military was deployed against outbreaks rather than trying to create a "fortress" against outbreaks.
