It seems that the most direct impact of on-chain "queue jumping" isn't really about who earns more or less, but about the predictability for ordinary people: clicking on a transaction sometimes inexplicably gets stuck in the middle, with slippage increasing, and the experience feels like waiting in line for breakfast only to be forcibly pushed into the queue... In other words, the sense of fairness is first lost.

The reason isn't complicated either; the ordering authority is in the hands of the block producers, and MEV is like picking up coins from the ground casually—after doing it for a while, it becomes a business. Recently, I've seen everyone complain about validator income and MEV, and I can understand. After all, on paper, it's "system revenue," but in practice, it feels like "I'm just a background extra." All I can do now is try to avoid chasing hot topics, set appropriate slippage, and use aggregation when possible. As for the rest... I'll just go eat first.
