Interesting. Thanks for the link also. I think you're right that under an efficient reputational system, people with good reputation would be rich and powerful. Indeed, that notion is implied in the title ("The Reputation Society") and is expressed in some of the chapters (especially the two last ones).

If your reputation mirrored your merits, this would also make society more meritocratic. If so, that would be the continuation of a long historical process. In the feudal age, you could be rich and powerful just because of your lineage. Thanks to the market economy, your income correlates to a far higher degree with your merits today. Efficient reputational systems would improve the functioning of the market economy and make this correlation even stronger.
