Halliburton and companies like it have literally developed the 3rd world and very little of that has to do with oil. It is in fertilizer plants, chemical plants, herbicide plants, LNG plants and terminals, dams, highways, even towns. and on and on. Almost all are financed by the IMF or World Bank through the governments of these countries.
Yes it is a risky business but it is also a very lucrative business. The irony is that oil related projects are only about 20% of Halliburtons market.
Thanks again. I learn something new every day.
