To be sure, tourism to Mexico is devastated and the country will suffer many economic problems (yes, real business cycle theory still is relevant these days). But is there any upside?
I hesitate to speak too soon but I'm actually somewhat impressed by how the Mexican government, at least at the national level, has responded. There have been many failures of Mexican health care systems at local levels but keep a few things in mind: a) some of the problems lie with citizens who won't go see doctors, or who won't go see non-shaman doctors, b) too many Mexicans self-administer antibiotics, and c) when there is so much air pollution it is harder to discover flu cases, especially in the midst of flu season there. Nonetheless Mexican reporting systems seem to have discovered an unusual flu fairly promptly.
Once the national government discovered what is going on, they acted decisively and without undue panic. There has been very little denial, a common feature in the early stages of health crises (how long was it until the U.S. government acknowledged AIDS?). No one is treating the Mexican federal government like a banana republic or a basket case or thinking that the Canadian government would have done so much better.
Am I wrong? Could this episode in the longer run bring Mexico closer to the community of developed nations? Might Mexicans now be more likely to self-identify with a government that is at least partially competent?
Time will tell.
