I see examples with this solution every day. There are curation guilds, trails, and groups of people who compile lists of quality content. It serves a purpose, is thoughtful and rewarding.
The problem arises where these people are paid to present someone elses content while the original author receives minimal rewards. No doubt due to similar reasons that you've outlined.
Another function that could fill this roll is resteeming. The issue here is that it's not rewarding at all and can be misused without even realizing it. (at least in the minds of your audience)
I think there are indeed better solutions and we should keep thinking to see what we can come up with that is fair, rewarding and effective.
