Sports, kinda. It’s possible to go unrewarded with them, but it’s very hard to go rewarded without them.
If you mean economic system, not really. Capitalism rewards having capital over everything else, communism (if we ignore the flawed attempts and go for theory) rewards everyone equally irrelevant of how hard you work or what your skills are. Though being skilled in something that’s actually pleasant as a job is a reward in itself as you won’t have to work manual labour.
