The majority of our time should be spent on worrying about ourselves, our 
    immediate circle of people, our neighborhood, city, country, planet. In that 
    order.

In response, I'm just going to quote Martin Niemoller:

    First they came for the Socialists, and I did not speak out—
    Because I was not a Socialist.

    Then they came for the Trade Unionists, and I did not speak out— 
    Because I was not a Trade Unionist.

    Then they came for the Jews, and I did not speak out— 
    Because I was not a Jew.

    Then they came for me—and there was no one left to speak for me.

Your approach rules out collective action on any kind of scale that can change the direction of a nation. There are always concerns at the family and local levels. What we need to understand is that sometimes concerns at the larger levels (country, planet) that outweigh our local concerns.

I agree with you regarding the importance of thinking and acting locally, especially for the majority of people who don't realistically have the power and influence to make a difference outside of their locality.

But it's a tremendously cynical and harmful to believe that "everyone is for themselves." It's just not true: there are millions if not billions of people who live much more for others than themselves. The supremacy of self-interest is not some foundational truth of social reality - it's an economic theory of human behavior which corporations and power hungry individuals want us to believe in because it props up the system of predatory capitalism that enriches them at the cost of the public good.

Interesting ego trap you've fallen into there.
