It is very difficult to lower EThereum's GAS fees because Ethereum itself has a POW system that anyone can set the transaction gas if they want to speed up the transaction and that is the effect of all the expensive GAS fees now on the market.
This is proof that Ethereum is getting more and more difficult to lower its GAS transaction fees, but there is still a lot behind it that BSC, Polygon, Matic, Solana can be like the Ethereum ecosystem but have low transaction fees.
