I don't think so, not in a society that values life and has access to the neccessities of life. We are taught to believe that people are naturally greedy or need someone to keep them in line. People will choose to work together if they are brought up to do so. We are currently raised to be competitive and dominant, at least in the dominant monetary system culture.
In genera, human is competive in nature. I we live on the african savanna, the bronxe age or in the 21th century. This is due to survival, we come from nature and to survive in a world with meat eaters, different weather and other human tribes. Look at children how cruel and also competive they can be? where does it come from? Human have had to compete for resources to survive all times, even brothers and sisters fights for attention. This are embedded somehow in the genes. I liv ein Norway that is general a very good country where the governement have been formed to take care of the citizens. But even though a good society, people compete. Some parts are learneed and other are inheritaged in the genes. Some have more than others. In general I think it will go centuries until human thinks more on the entire species. Why, because people around the world are in different phases. Some societies are in the midle ages regards human thinking, others are poor, others are so rich that they only want more and do not se the exploitation. And others go to war, to point view outwards. Because we all not are in the same level the first society that gives 100% to humanity will be eaten by the other wolfes. To be ideal and kind is dangerous. Thats my personal experience and the lesson from history.
What is working in long run is NATO, where countries protect each others from enemies that treathens one of the member. This makes a environment for growth inside this borders that can be of examples of the wolfes outside. To create a society that takecares of the citizens and appreciate them as equals, rather than expoit them that many societies does today. We need UN and a defence alliance like NATO, just because the entire world is not on same level regards to maturity.
but I do not support, war, expoitations or other. But in history idelogies is one of the things that have killed most peoplein shortest time except maybe from diseases.
