Short answer is genocide of native people combined with racism against Black people.
Mixed-race marriage, neighborhoods and schools were illegal in the US, in some way or another, for over 300 years. The US Supreme Court did not rule it unconstitutional until 1967.
The US state of Alabama did not officially remove their laws against mixed-race marriage until year 2000.
Tried Wayland about 5 years ago to see what all the hype was about, with Nvidia proprietary drivers, got a black screen. Could never get beyond that. Went back to xorg.
Tried about 3 or 4 years ago, with amdgpu drivers, no black screen this time but chrome would not work and a few other programs didn't work right or at all. There may have been special builds or wrappers to work around some of those issues but I had no interest in dealing with that at the time, so I went back to xorg.
Have not felt motivated to try again as I haven't had any issues with xorg. I'm using Nvidia drivers at the moment. I also heavily use turbovnc server with virtual gl and not sure how (or if) that'd work in combination with Wayland.
I haven't had to even think about the fact I'm using xorg or screw around with the configuration in like 10 or 15 years. It just works, for me and my setup, anyway.
