remember that are not the miners that make the fee, they could accept even the lowest fee if everyone was using the lowest one and reducing the average, it's up to the peple that decide what fee to use
if for example everyone start now to lower his fee the average would be like the old 10k satoshi per transaction, but instead everyone is rushing to have his/her transaction prioritized and this is increasing the average, miners have no fault here
I'm not so sure of that...
I mean why would the miner not simply agree to not accept a transaction with fee lower than X
or even do the transaction while putting fees themselves to make higher average fees...
I've seen blocks not full at all, doesn't it mean that miners are refusing transactions in some cases?
because if everyone is going to send transaction lower than x, then miners will have no choice and choose those transactions anyway, i means miners can't decide to not include any transaction, they must do it
after all minins is the process to include transaction in a block and get reward from it, by rejecting all transaction they would destroy their income
