Don’t you still see this with hip-hop to some extent?

I also think a lot of the difference is that a much smaller percentage of the population grows up as poor as she did. A person from a similar wealth/income percentile today mightn’t seem to have had such a difficult start.

Obviously lots of other things are different today – it’s easier than ever to access a wide variety of music but that’s not what people tend to do (iirc); there’s less money to be made selling music; there’s perhaps less interest in more ‘rural’ genres of music.
