America Ferrera proclaims, “For 17 years of my career, I have witnessed the power our voices have when they can access presence in the culture. I've seen it. I've lived it, we've all seen it. In entertainment, in politics, in business, in social change. We cannot deny it -- presence creates possibility. But for the last 17 years, I've also heard the same excuses for why some of us can access presence in the culture and some of us can't.” What does she mean about accessing “presence in the culture”?
