How many of them where legally excluded from owning property?
Do you really think that comparing the U.S. an industrial nation with nigeria, a country which was until 80 years ago literally owned by another nation?
I don't claim anything, all I do is to show you that your "stats" are completely invalid.
Honestly, I don't care, I just think it's funny how bad you guys are with stats. None of these things pass the first most superficial test. I mean comparing Nigeria with the U.S... At least compare nations of the same development level. For example you could compare egypt with chile or something like that
