[Azkron]

For many people "wealthy = evil". And "poor = good". It is easier to demonize someone that is doing better than you than to admit that maybe he is just making better choices.

The poor can be anything. A wealthy person could have worked hard for it. A wealthy person could have also exploited others in order to get wealthy.

Virtually all (meaning systemically) very wealthy people had to exploit others to get to their very wealthy state.
