It's a hard problem because it reduces to the fact that narcissists and sociopaths are a significant proportion of the population, and they're strongly attracted to money, power, attention, and status.

So even though they're a small minority they infest politics, business, and the media, and create a culture in their own image.

Most proposed solutions end up in superficial tribal arguments about standard economic and political positions. Not about the underlying issue, which cuts right across the usual battle lines.
