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
You got it right, it's all about people's decision. I only use low fee (satoshi/kb) for my transactions and turn what I want to spend into other safe coins, like ETH that have better fees. My purpose doing this is because I disagree with fees scaling with the price (in usd), for now, people don't mine for the fee, they mine for BTCs and fees they get are a plus, so I'm pretty sure that if the majority applied low fees (satoshi/kb), then it would become normal.
