"Contributing to society" is a very broad and ill-defined subject. What I may consider beneficial, others might not see it that way. It is very subjective.
Pagerank solves this though right? Everyone can choose to rank certain professions/people every few years, better than we have now.
That isn't an appropriate description of how PageRank works.
Do I have to provide a link for you? I'm genuinely serious about everyone ranking (linking = rating) each other for positive contribution to society and then allowing them to have more of a vote. Maybe rankings would be a bit more like chess than PageRank but I'm convinced we could come up with something fairer than it is now.

I'm not sure what you mean by this. Here are some links I'm providing to you.
