> I don't. When I make decisions that might benefit me but affect others, I consider the impact on others before deciding what to do. Sometimes (often?) I choose the option that benefits me less (or is neutral, or hurts me), if I believe the negatives to others are too high.

I didn't say that means they don't consider others, and I haven't taken a survey of everybody on the planet.

Obviously people believe their interests weigh more.
