"In other words, the quality of the most important part of health care treatments bypassed the rest of the problems in poor economies and grew rapidly, even in countries with only so-so economic growth. The rate of reduction in child mortality has tripled in many countries since the 1990s, and by no means are those locales major economic winners as say Singapore and South Korea were.
Therein lies one of the most important (and under-reported) global changes in the last twenty years. It is now possible to have a decent public health system in a country with poor or mediocre political and economic institutions.
In other words, public health is no longer such an O-Ring service, an O-Ring service being one where everything has to go right for the service to be of decent quality. And advances are much, much easier when the O-Ring structure no longer rules."
