It is sad to see this post, I see what tou mean, the sad part is when someone is on top they might forget that they were once on the bottom of the chain, therefore, Primadonnas are at their best.
The only thing I can say is: do kot ruin it for the rest of us that are trying to make a better life for ourselves and the community. Sadly, you cannot control greedy people. I wish there was an antidote against that. All we can do is keep our fingers crossed and maybe we could find out a real solution against this problem.

Blessings!
