Why do people see capitalism as a bad thing?

I'd have to say that the most powerful and enduring law of nature would have to be competition. It's called survival of the fittest. The whole world is one big free-for-all, and every species is in competition with one another. Every person was born to live in their best SELF-interest. Greed is the driver of everything every person and animal does. Many people hate that we are destroying the environment and wiping out countless other animal species. What they don't understand is that we humans, like every other species on this Earth, were designed to do just that. People like the idea of a world where we all live in harmony together and prosper. Unfortunately, there aren't enough resources to support. The strongest, most adaptable species survive, while those that can't compete die off. It's nature's way of ensuring only the strong live and the weak die. Humans, with our superior technology, are constantly adapting with our constantly changing world, and any animal that can't compete with us is destined to fade into the fabric of time. Believe it or not, we are animals, too. Just really smart animals. We use our technolgy to make up for our stunning lack of physical strength. We are just doing what we were supposed to do, which is to rise to the top and dominate the earth. You may think that this is way too harsh and can't be justified, but you must remember that the morals we have are primarily a human attribute. Nature doesn't discriminate. Life is just not fair. Now back to the base topic that I have until now, ignored. Capitalism is simply modeled after the law of survival of the fittest. The rich are the most equipped to further our society, while the poor really have no means to do anything in particular. So, all the wealth winds up with the richest few who can make something of it. Income inequality is simply modeled after the food chain in nature. This is what capitalism does. It doesn't discriminate based on how we achieve our wealth, all that matters is that we do have it now. If you don't like it, make something of it. We are all entitled to do whatever we can to get ahead. People love nature, but hate capitalism, when they are really the same thing. Doesn't make much sense, does it?
