Nitpick: The US Voting Rights Act became law in 1965 [2], which is more like 60 years ago. Not sure if that's what you were getting at with "basically an apartheid" but it was the closest concrete landmark near your 50 year timeline.

(since posting Wikipedia links seems appropriate.)
It’s not Ragnar Lodbrok turning into ABBA. It’s a mostly peaceful peasant society getting tossed around by history until it became a mostly peaceful service economy - and the shaking never really stopped.
History is not a straight progress line. Ask the Romans.
Ask a medieval peasant and he wouldnt even be able to describe how his life is different from his father's.
That «multiculturalism» is already responsible for undoing the changes you’re describing here. Sweden is regressing into a medieval, middle-eastern ghetto faster than you’d think - as do other parts of Europe.
These sort of hyper exaggerated comments help no one. Not to mention "other parts of Europe" were literally Islamic for hundreds of years.
