Under capitalism everyone decides what to reward, even the poorest people in first world countries make tons of decisions what to spend their money on, that is how we decide merit, if people decide to give you their money you have merit. We try to regulate so it doesn't get abusive but there will always be some holes, but that system is as close to an unbiased merit function we have gotten. The other good merit function we have is one vote per person, that is how we elect national leaders, this doesn't have some of the abusive loopholes as the capitalist merit function, but instead it has other abusive properties which is why every modern country choose to do a mix of both.
