Because good is service to others. Not yourself.
The universe rewards the more efficient way. It's always better to take the shortcut than the longer route to get to somewhere, right? Saves petrol, frustration, mental, physical energy, etc. The evil way is a very efficient way. Good is neglected because it is extremely wasteful of energy and inefficient.
I would have to say it doesn't. There really is no evil or good. People on earth are just learning and evolving. There is a reason for the nature of each person's reality. It is all karma and LOA. Thoughts become Things.

To reward good people, we've hereafter.
