Edit: and on topic towards your post. Yes, if we all would align as human beings we could create a mutually beneficial world for everyone, however, we humans aren't wired like that. Different people aim for different goals, and many are selfish in the short term (maybe just because they lack the intelligence to see the negative impact of their actions down the road).
