We clearly have problems with people not giving a fuck about most other people, that's easy to see. But I wouldn't go label a huge swath of the US population that way. Realistically, we're looking at something like 1-4 percent of the population. Granted, that's still millions of people, but nowhere near the majority.

What may be the bigger problem is that our society selects for people with sociopathic tendencies in high office, police, and powerful positions in companies. IMO, a kind of modeling effect is more likely how this impacts everyone else.
