Blue: Maybe we should not feel so superior, if resistance to antibiotics continue to develop we may well see a similar curve in the rest of the world. Even the most simply surgery could become very dangerous, many elective operations/procedures would be too risky to do (even getting a blood sample would become more dangerous), lots of children could die from today easily treated respiratory infections, even healthy adults could quickly die from a pneumonia or urinary infection.
That is my conclusion also. These data show very clearly that life-expectancy may not rise ad infinitum, but after a certain period of increase, it can decrease dramatically. This doesn’t mean that “there is nothing to do”, after all the decrease has physical causes and can be remedied by physical means. But the possibility and problem need to be recognized. And yes, this can happen everywhere. Moreover, this happening in one place can swiftly carry over to another – infectious diseases are still the worst enemies of longevity.
Alex: Why was the West interested in investing in South Korea? Because they had sufficiently strong property rights and other aspects of economic freedom to create business opportunities and attract investment.
Yes, that, but perhaps also the fact that if they didn’t invest into the development of South Korea, they would have yet another Soviet satellite state, or rather one large North Korea with doubled power and aggressiveness. And the same can happen also in other places. It is my belief that strategic, concerted investments will be necessary for Africa, investments into education, health, industrial infrastructure – all the things that will absolutely not bring immediate profits, but will in the long run contribute to the stability of our world. The “laissez-faire” principle has been dead for 150 years, it’s just a shame that so many transhumanists are trying to revive it.
Alex: How much money have you voluntarily donated to pull the Africans' economic weight for them? If you are like a typical American then it's not anywhere as much as you've unwittingly spent to aid in the development of more economically free countries that export food, cheaply manufactured plastic goods, clothes, etc.
The involvement at the personal level is indeed the real question. Donating a couple of bucks or volunteering for a couple of hours may indeed not make much of splash. But still, it may do something, at least raise the awareness in some small way. I am not a “typical American”, I am a typical or atypical Israeli

And Africa is right here across the border. Several of my acquaintances have participated in development projects in Africa (such as building electric power stations, of course for a pay, mostly governmental pay, and not out sheer altruism), but not myself personally, of which I am almost ashamed. I wish I could do more, but I am just not sure what. And of course, a lot of things are done for the kinds of rewards that are not necessaritly monetary.
