The mistake is thinking in terms of linear social progress, which is trivially perverted for rhetoric. People are certainly more civil and aware of acute racism and racial discrimination. But in material terms, being black makes you acutely more vulnerable to all of society’s problems: poverty, prison, poor healthcare, poor access to jobs, poor education, low wages. The civil rights movement—and MLK’s life—ended before addressing this. More relevantly to now, only 1 in 5 black Americans are able to work from home. Segregation still exists, it just largely uses other mechanisms today other than red lining and direct racial discrimination in businesses and government. I recognize claims similar to “we”re doing better now than we were in the 50s” as one technique of many to focus on social, not material or systemic, gains, though I suspect in many cases this does not come from an intent to do so.
