The situation in the USA for nonwhite people has improved dramatically *in some areas.*. It was not that long ago that a black man with a Ph.D. could not get a job higher than janitorial work This has changed (it still has a long way to go). On the other hand the conviction of Derek Chauvin was remarkable, trailblazing, pivotal, because for most of my life a policeman who murdered a black man in cold blood could do so without fear of reprisal, not erven the loss of a day's pay.

At the other end, though, racist attitudes among a large minority of Americans have not substantially improved at all; quite the contrary, Trump's "plain speaking" on matters of race has liberated and encouraged these wretched people. Bigots are angrier than ever.
