Have the values and attitudes inculcated during slavery actually survived into today, one generation passing them on to the next?
It seems to.
Or perhaps by cultural impact nwr meant how whites react to black culture, which would be a replenishment or reinforcement of racism when whites experience black culture as scary or intimidating?
No, that's not it. The reaction to black culture should not be that different from the reaction to other cultures. But American racism is different from that.
I grew up in Australia, and came to US as a grad student. And I found the racism quite shocking. I suppose I should have expected it, having watched American movies, some of which romanticized the era of slavery. But it was still shocking.
A common white American attitude toward blacks is that slavery ended a long time ago, whites are no longer racist, and whites are not responsible for blacks' lesser income, wealth, education, housing, health care, etc. If blacks want a better life then they should work for it, just like whites do.
I agree with that principle. But if fails to recognize all of the aspects of culture that make it difficult for blacks to get a good education and a good job.
I think part of the problem is that conservatives like to reminisce about "the good old days". And that means the days of slavery.
