So there are two issues here. The first is the fee market. That's working exactly as intended. Ethereum didn't exactly "break," it just didn't have the scaling to handle the traffic, and prices rose accordingly. The second issue is the scaling, and everyone in the community agrees that Ethereum needs to scale a lot better. There's a lot of work being done on that front, including rollups and sharding.
