My recent travels were in a Third Worldish country, and my big conclusion about the lack of development in the parts that did lack it, information the World Bank should pay me millions to provide, was that there was an appalling lack of rather easily produced public infrastructure. One can't just wave a magic wand and make it appear, but it should be a priority in ways that it didn't seem to be.
In this country with 10% unemployment and some places with massive public infrastructure needs, the solution is also obvious.
