Also I don't understand why, but your comment defaults to collapsed. That is a shame as it's highly relevant.
The USA has spent billions of dollars in the last century on trying to help African countries, but all it's realistically really led to is just more people in need in Africa. What happens to all those people that have become dependant on the aid when the US economy crumbles and there is no more money to send overseas?

Western people suggesting Africa is an un-helpable backwater has been common for decades. Bill Gates likes to talk about all the progress made, in fact.

You're correct that this inability to upkeep infrastructure is in stark contrast to those many places about the globe that have never had electricity or water delivered to home dwellings.
Such places typically get by generation to generation and look after what they do have .. and are often removed as communities from what outsiders seeking local community resources see as necessary to support the take over of local community and imposition of third party extraction.
You're correct that China hires US PMC's to secure the take over of generational land rights and build roads to export "water" in the form of agricultural products, etc. You're correct that local communities see unsecured roads as a resource of good gravel, etc to be used.
