Steemit is a great example of financial motivations indeed and is set up in a way to reward those who work hard instead of participants who try to take short cuts. Although, even Steemit seems to have some areas where rewards can be a bit unbalanced.
In terms of government, I would like to see contraints where politicians could not cross into private sectors they played a role in governing previously, or have influence in. Currently, financial motives are plagued by conflicts of interest.

I do like the idea of creating a rating system where incentives are delayed but that idea in and of itself has problems. For one, how are the incentives being secured until payout? We are already seeing hard working individuals who were counting on their pensions in financial strain because the money promised to them was spent. I would also worry that the rating system would lead to blackmail or threats of the children in care. Even though the rating would take place as an adult there lies a possibility for years of, manipulation to take place in the meantime. Although, I do admit delayed gratification would be a better route than the current system in place.

I am adding your books to my reading list! As a mom of young twins, I may take a while to get through them but I definitely think they are worth a read.
