No. The very tribalism that has allowed us to survive now works against us because we were too successful at survival. The solution is to be aware of and constantly fight against our base selfish instincts through things like what you said. The problem is that we seem to always go back to “fuck you, got mine” as a species. Perhaps the great filter is that a species that’s successful enough at survival to get to the point where space travel is possible will always be betrayed by the tribalistic behavior they needed to survive the harshness of life.
