This is the important part of the question:
Why are there miners at all? What do they do? How are you better of with them? Why are you giving them payouts? Why do you care if they are happy or not? Why do you call them miners instead of parasites?
This is a little harsh to say since miners do a specific job.
We cant expect regular users to fill in for miners.
Therefore, a solution has to be found for a fee structure that is good for both miners and users.
