Perhaps it's the people with poor impulse control and lack of education that end up economically poor. Maybe they never learned better.

Taking pleasure from those less fortunate than yourself is a trick of the ego. It makes you feel better about yourself by labeling someone else inferior. It comes from a place of insecurity about one's own worth.

By simplifying the problem to a group of people simply being inferior, you miss all the nuance, the complex system of factors that created the result.

It's much easier to dehumanize. But if we don't counter these primitive tribal urges, we are bound to repeat the tragedies of history.
