Sometimes I think we need to be realistic and accept that there are populations on the planet which have a hundred - or hundreds - of years of work to evolve past their current mindset. I can think of a number of countries where the general population does not seem to have the capacities for this type of responsibility.

A deep education on civic duty rather than nationalism is one obvious piece of the puzzle, but also a safety net and affluence where people are not desperate and can remain free of basic economic pressure to conform is another big one.

Including philosophy in education from a younger age can help with instilling that mindset.
