I think you have no idea about history. There is only one empire that subjugated 80% of the world population and that's the European empire. No one comes close, not Rome, not the Vikings, not the Normans, not the Chinese, not Genghis Khan, not Japan. Europe alone has dominated the globe for 600 years. What you call "the entirety of human civilization" is actually only white European society. Africa did not extract trillions of dollars from Europe. China did not extract trillions of the dollars from Turtle Island. The Aztecs didn't extract trillions of dollars from Siberia.
There is only one society that has done this and is still doing it and it's the European civilization that is anchored in the North Atlantic.
You claim reparations will never happen, yet ignore that reparations we're paid to slave owners when they lost their slaves. In Haiti, it was cheaper for the French to buy 50K new slaves every year than it was to keep slaves alive. They worked 10s of thousands of slaves to death every year. When the slaves finally revolted and killed all the French on the island, the French levied a debt on Haiti to cover the cost of reparations to the slave owners. That debt is still being repaid.
So don't tell me Europe can't make reparations happen because it can and it has done so. The North Atlantic empire is a white supremacist empire that has been dominating the global majority to the enrichment of the ultraminority and has done so through the invention of structural racism, racialized capitalism, and monopoly imperialism. They chose to ensure reparations go to the minority white slave owners and steal those reparations from the very people they enslaved.
