Black women get more lenient sentencing for the same crimes than white or Hispanic women. So you should reconsider your stance from being about "the mass incarceration of non-whites" because it's a lot more complicated than that.
Those people from the 60s definitely had a hard time but I would say that anyone born in our generation had the same opportunities available regardless of race. Unless you live in Alabama or something.
