It's clear that most people don't care about what happens in the world unless it happens to them.

I would say that such is normal. If it's supposed to be the other way around, which by the way is very en vogue and politically correct, that people care about what doesn't concern them yet, you have a life in the subjunctive, as I see it.

If I re-formulate your sentence it could look like this:
people don't WORRY about what happens in the world unless it happens to them.
For me, that sounds reasonable.
I would even go further and say:

I shall not worry what "people" say or do or don't do. Of course, I would like my attitude to be picked up. For me, it would be fine if only the members of my family would not worry about themselves. But then, I look at me again and come to the conclusion there is some change of attitude ahead, how this me deals with life.

From the disinterest I perceive I conclude that what I publish myself cannot be seen as taking one side. It does not feed the pains and pleasures. On light days I laugh about it. On darker days it frustrates me.

I, at least, have read some of your book recommendations. I would like to recommend reading Alan Watts. Here, one link:
