Pointing to unusual people, then claiming that proves they exemplify what should be usual…

That isn’t an argument or solution for anything. That’s state some fact, then state your desired conclusion, without even an attempt at reasoning in between.

Show me any community that turns their success demographics around. Someone pointing at a few successful examples, and saying everyone should do that, won’t be how they did it.

People have suffered in disadvantaged demographics from the dawn of time. They are real. Nobody wants differences like that to exist, but they are pernicious. Context has a huge impact on people and bad contexts are often very self-reinforcing.
