I use 60-70 years as a conservative number, so that even the most fervent believers of "it's not because they are black, it's because they are poor" (or similar opinions) can see that people still alive today were likely legally discriminated against based on the color of their skin in ways that most people take for granted.
I would agree that things like redlining and discretionary funding appropriations are still an issue worth discussing today.
