Due to the intensive traffic, the ETH network has limited traffic handling capability. Users wanted to do their transactions faster than others, so they paid more fees, and when a few thousand users are doing this every minute, just think what would happen. This problem will be solved with the new upgrade the ETH network will have. This is set to happen around March, so i guess gas fees for the ETH network will be reduced 10 times compared to their current situation. With all the layer 2 eth gas fees isn't a problem for the majority.
