This needs investment also. An investment poorer people cannot or do not want to do. It is reasonable that when someone gives up a couple of things because that person is rich (rich as in a person in the developed world) the sacrifice is more or less acceptable.

Now change environment and think that these sacrifices are way worse. Even worse than that: that has more implications in conservative cultures where, whether you like it or not, showing "muscle" (wealth) is socially important for them to reach other soccial layers that will make their lives easier.

But giving up those things is probably a very bad choice for their living.

America cannot be compared to South East Asia economically speaking, for example. So the comparison of the coal centrals is not even close.

A salary in Vietnam is maybe 15 million VND for many people. With that you can hardly live in some areas. It is around 600 usd.

Just my two cents.

So here I go: if it is so stupid, why it is not done yet?

Try not to blame anyone. Do it rationally if you can, from your message I understand your opinion.

I say this as a person that has lived in a developing country the last 15 years. It is not that simple IMHO...
