Communism is a solution to this, maybe. Almost everyone is equal. Everyone - though having different professions and working in different ways - earns almost the same.

I guess this might be kinda bizarre but I think an extension of Darwinian theory kinda explains this. I think this approach to the world, that you lament about, could be the way that could be most effective for the progress of our species. When everyone is "equal" under every condition, there is almost no incentive for anyone to work real hard. So, there should be a reward structure that motivates people to work hard. So, there is this structure in our society that embeds in us this way of approaching the world in which we try to get as much as we can for ourselves. And in doing so we benefit the world by some amount. See the progress in science and technology - we know so much, can manipulate so much. We have already accomplished a lot of things that our religions say "gods" do, and with time this difference between gods and us will only decrease.

There are always some negative effects though. Some people will not want to work hard but will want that reward. They search for shortcuts. So, there's mess.
