Maybe we would be living in a society where we judge people more on their qualities as a human being, and less on their physical attributes. The things that we can't control like gender, age, and race wouldn't matter. What would matter is how we have contributed to the world that we live in. Our contributions are something we each have a great control over. We each make a conscious choice of how we want to add something to the world around us.
Every individual has sole responsibility for what course their life takes.
Unfortunately, we don't. At least not yet. Stop dwelling on how things could be and start thinking about how things should be. There is nothing we can do to change the way that history has turned out so far. However, there is lots we can do to make sure that our future is better than our past.
