A great deal, if not the majority, of human conflict can be understood through two competing perspectives: 1. There are immutable moral principles that are embedded in the universe like stars in the sky. 2. Moral principles are a human invention that shift with time and place. Capitalism is a morally neutral system, so it doesn't care whether you become a billionaire or spend the rest of your life sleeping in an alleyway. We are probably capable of designing an economic system that is equally (if not more) productive while being less destructive of the environment and human soul, but we're largely distracted by maintaining the current one. As a worker, you are not an "associate", "peer", and certainly not "a member of the family." You are a unit of productivity and totally expendable regardless of your level of devotion to the job and years put in. Countries exist to compete against other countries for resources; nationalism and patriotism are the means by which populations are brought into compliance with that vision. If you're an American, chances are that you talk too much about your personal life. This is a symptom of the confessional culture that has emerged since the proliferation of talk shows since the 1980s. At some indeterminable date in the future, the last human being will draw her final breath and our species will become extinct. Should an alien civilization discover Earth and its artifacts, after watching a few Youtube clips, it will only take them seconds to know why we no longer exist.
Were I an alien approaching earth and picking up our broadcast signals, I suspect my reaction would be a quick call home "Don't let these creatures out of their solar system. They can't even get along with each other, and they've made a good portion of their planet into a waste dump. They're polluting their air and water, and impacting the entire climate of the place. They are much too dangerous too allow out into the galaxy unless and until they grow up."
