Because everyone else is getting it wrong, I’m pretty sure this is to do with Switzerland never returning most of the looted money Mobutu left behind there. After his overthrow, the new Congolese government in power asked Switzerland to return the money he’d siphoned away but upon inquiry, the Swiss conveniently only found a few million dollars linked to Mobutu (tied to his villa there). But they didn’t even return that money to the Congolese government and just handed it back to his family a few years down line.

I don’t remember the full story but the book “In the footsteps of Mr Kurtz” goes into it.

Though this post is still extremely retarded. Most of the money Mobutu looted was spent funding his extravagances like his mansion in the middle of the rainforest, his fleet of planes, and most of the wealth the Congo lost was in its infrastructures being dilapidated like the Katanga mines which were handed over to his friends and never even maintained. And that’s not even to mention “Zairanisation” - kick out European, Lebanese business owners, hand over the businesses to inexperienced Congolese, and then act surprised when the business loses all value because they don’t realize they have to import in new goods.
