The residents of Zimbabwe (formerly Rhodesia) were surprised how fast things when to crap once they chased all the Whites out. Same thing is happening in South Africa. It’s really a no-brainer.
I grew up with yearly visits from white, Rhodesian farmers that were close friends of my father. They fled and years later when we were discussing the decline of Zimbabwe, he told me this joke. “Do you know what we used to light our homes with before we had candles? Light bulbs!”
It is happening in America’s inner cities, and creeping out into the suburbs as they are abandoned to imported Third Worlders. When the government mentions “crumbling infrastructure”, you have to separate those projects that serve viable, productive populations (who can contribute to the upkeep) and those in areas where a W-2 hasn’t been issued in half a century. No reason to address the latter (or provide police protection, schools, etc. - they won’t pay for them anyway).
