The only reliable solution I know to that is for people to be principled.

...and educated.

Today it seems like we've lost that almost entirely.

We replaced it by egoism. Through decades of neoliberalism we are taught to only care about ourselves, not our communities. Making money and buying things became our main philosophy. It does not matter if you are actually well-off, everyone is in a race with everyone else.

As a result, we don't stand up against injustice as long as it does not affect us much. And the egoism makes everything seem like a zero-sum game, if an immigrant gets a house paid by taxes, then I must be losing something.

This is also what permeates current US policy - you can only win if someone else loses. In this mindset it is not possible to have cooperation that is mutually beneficial.

I hope we can heal as mankind and take care of each other again.

For sure, I agree education helps and could be considered a prerequisite to someone really be principled to begin with. It takes wisdom to learn what matters to you and to see patterns behind any particular topic of the day, and wisdom only comes about through education and experience.

I am always torn a bit on education as a goal though. I don't like centralized education, it makes it much to easy to lead to similar problems we have today when any small group of people can decide what and how every person is required to be taught.

We need people educated by their own choice, going down whatever paths they find interesting and learning from that journey. Its my belief that people are generally good, and given the time and space to find their own core principles, and a Democratic type of system where our voices can be heard, things will generally work out for the best in the end. I'll always take the collective opinion of principled individuals over the strongly held views of the small few in power at the time.
