ETH needs something more than a simple upgrade for fees to remain as low as possible. This is normal for a blockchain network that's widely popular in the mainstream world. We should give ETH some time before it scales for the masses. It's hoped that subsequent network upgrades will remediate the "high gas fee" issue. There are other cryptocurrencies with lower fees and faster transaction confirmation time anyways. So I don't see high fees becoming much of a concern since people can choose another blockchain network to avoid paying high fees and long wait times. Those who care about decentralization will choose Ethereum regardless of the issues mentioned before. Slow and steady wins the race, so I believe that ETH will remain as the "King of Altcoins" for a very long time. Just my opinion
