The reward pool is a common. Stakeholders can use their vote to express an opinion about whether a post is currently under-rewarded or over-rewarded. That should be normalized.

The highly-rewarded people whose posts get downvoted are a diverse bunch in terms of how they react to the downvotes. Some take it in stride. Others start whining and complaining at the first downvote making a huge production out of it. It's the human ego at work. Those people should grow up. It's always a huge source of second-hand embarrassment when people one of whose posts goes, say, from $50 to $35 throw a fit.
