While it would be a mistake to glamorize Mexico's health coverage for the poor through Seguros Populares, it is not a mistake to say that here where I live, it does a significantly better job than Medicaid, at least as I have known it. I don't think it's improved. In our Colonia, lots of people have used it to have babies and to treat serious diseases including cancer and diabetes heart disease and mental illness. It does not always adequately cover the cost of medicines, but it always is available in emergencies. I can only claim personal acquaintanceship with one dr, the pediatrician Dra. Jania, who is incredible. The right to universal health care is written into the Mexican Constitution, so failure to provide it is considered a grave flaw.
So add this bit of information to your armament of defenses against those who would trash Mexico.
