Read about the India Pakistan partition. How would you feel if you have to leave behind everything you have and move to another country because someone decided it is so.
Plenty of people built their lives on the US being a British colony. Plenty of people built their lives on Austria and Germany being a single country. Plenty of people built their lives on the USSR being a single entity. I could go on and on listing examples. Why is everyone else allowed to naturally form their own national identities but recent (particularly African) colonies are supposed to suck it up and endure the empty ones forced on them?
If the borders don't really matter, then redrawing them does no harm.
And if that won't fix much, then your talk about sunk cost is pointless.
People understand/respect separatism when it's Kosovo, Scotland, Catalunya, Hong Kong, etc, but all of a sudden want to be led by the hand when it involves African nations.
But the context was about economics, so I presumed that you were saying that it would be economically helpful to change the boundaries.
This obviously does not apply to all sub-Saharan countries - there are many that already had or have managed to forge national identities of their own. I am speaking for those of us who are unevenly yoked and know it.
European borders went through many, many bloody revisions as well, yet Europe is still quite prosperous.
That is besides the fact that (for example) there are far more extant ethnic groups in my country alone than in all of [Western, if not the entirety of] Europe - the considerations when it comes to building a nation are simply not the same. There's nothing that irks me more in these discussions than "Why haven't you already done what took us centuries to do naturally in the space of a few decades under artificial tension?"
European borders were most certainly forcibly drawn.

All I'm saying is that the border argument seems weak.
Before America was colonized, there were also political divisions and multiple distinct cultures. Then, a new culture showed up and eliminated all of it. Rightfully or not, it was the establishment of unified central authority that gave America its prosperity. Go look at a map of North America and notice there's only three big countries. In Africa, the situation is essentially a stalemate because there are so many competing factions.
A group of small nations is always going to be more inefficient than one big nation. Just imagine what would happen if you abolished the federal government of the United States.
The earth isn't just a bigger New York.
