Fees will normalize only after eth 2.0 release or after defi death. I dont know what will be sooner
These two factors could be the cost recovery of expensive ETH gas, but maybe this is the business game of the big miners. They are still hungry for profit, all will be done when they reach their goal.
Miners have nothing to do with this but those who are trading on the uniswap has been making the fees were going so high or we can call that has already reached the non sense position when the amount of tx is less compared with what they must gonna pay to the network to deliver their transaction.
this is not a business but those crazy defi traders were making this.
