I have a sense that if we all had clarity and perspective, the vast majority of us would actually come into a much tighter path forward as we realize that our goals are much more aligned than we had envisaged.
This would be amazing if it happened, it would basically mean we would enter an Utopian age for humanity and there would be no more wars and fights over silly things, because at the core of all things, we all humans want the same thing, to survive, progress and have a little bit of happiness along the way.
But its a bit hard as you say, because every human being lives inside its own bubble and then we trap ourselves in bigger ideological or religious bubbles that prevent us from seeing whats best for us, I truly believe we can set aside our differences and wars to work together.
We want to feel a part of something even if it is harmful or there are better options available. we are creatures of habit, that is all culture and traditions are.
