Why do harmful people seem to receive the greatest rewards in life?

A good example of this is bullies. While the idea that the bully ends up a failure and the victim becomes successful is a popular theme in media, it doesn't seem to hold true in real life, at least not in my experience.

Many people who are genuinely awful seem to have it all—they get a good education, have a successful career, their own home, car, family, and a thriving social life. Meanwhile, the victims of these people often have little to nothing.

Some might say, "Well, they’re probably secretly miserable but just act happy." I don’t buy that, because no one really knows that for sure. They might not be miserable at all. It’s just baffling to me how life seems to reward terrible people, and they go through life without facing any consequences. Karma doesn’t seem to exist.
