It's all about access. YC can only fund the best applications it gets. Those often come from, I'm guessing, people whose creative sides have been nurtured while also getting some kind of constructive exposure to programming. Just like anything else, the socio-economically disadvantaged often don't get the access or education they need to wield or understand the power of programming. I do think that is changing, as evinced by the programs and organizations that have sprouted up to address the issue. But it's a slog.
