There are lots of other problems we should tackle, too! But presumably many of these are just symptoms of some deeper underlying problem. What is this deeper problem? I’ve been trying to figure that out for years. Is there any way to summarize what’s going on, or it is just a big complicated mess?
Here’s my attempt at a quick summary: the human race makes big decisions based on an economic model that ignores many negative externalities.
A ‘negative externality’ is, very roughly, a way in which my actions impose a cost on you, for which I don’t pay any price.
