Places like SA and Rio collapse in the sense that:
1. Nearly all government is corrupt. No government functions work as intended.
2. Being in public is very unsafe for white or otherwise non-black looking people, leading to separate neighborhoods with guards, etc.
3. There are high levels of gang violence, wars for territory or drugs, etc. This does not mean actual warfare like Ukraine or even Syria, they're not capable of that level of ambition and planning. That and governments will usually have some kind of connection to the openly criminal groups. Instead it's more like an ongoing low intensity guerilla war. Ironically this means statistically it's less safe for blacks than for whites, simply on account of how many of them get involved in criminal activity and end up in a ditch.
4. The national identity irreversibly changes with the demographics and the zeitgeist of the masses, and this is a continuous process. So all in all there is no moment of collapse, only a slow decay until it's clear that the country you grew up with no longer exists, itself having been a mere shadow of the country your grandpa knew and so on.
And it all starts with

Once you have women and retards of all sorts having a say in things, death is certain.
In short, "The American Republic will endure until the day Congress discovers that it can bribe the public with the public's money."
This is what universal suffrage gets you.
