The Whiners have the ability to enhance skydives. Their eagle eyes spot imperfections in a dive. They point out to the jumper next to him, exactly the whys and wherefores about how terrible this dive will be. They know a better plan and can tell it to another jumper. These jumpers remain part of The Whiners because they never take actions to implement their know-how.
Nothing is gained by complaining after the fact.
Rights for complaining belong to those who contribute to the dive. Make a suggestion for an alternative method based on some problem. Republished with permission.
