I don't knock our elders. Without them, there would not be such a large black middle class today. It's not like the percentages have remained stagnant since 1965. Quite the opposite. More folks from the lower class have been able to move up, get educations, build homes, and create more opportunity for themselves.
That being said, we need to focus our attention and the 33% of us who are not considered middle/upper class. We need to rebuild our institutions, banks, businesses, places of worship et cetera.
And as for your first point,
2 + 2 is not the same as x^2 + 5x + 6. So even though you might find problems all over the globe, oppression if you will, not all of them are the same.
