Recently, I saw retail investors complaining again, "I just clicked confirm and someone cut in line." To put it simply, MEV isn't about affecting a "mysterious big whale"; more often, it's about small swaps by ordinary people: you think you're trading at the price you see, but in reality, you're squeezed, slippage eats up your entire amount, and that tiny difference in your wallet is someone else's "ordering profit." What's more embarrassing is that when miners/validators see their income rise, everyone instinctively feels that this system is unfair... I now only dare to set more conservative slippage, preferring to trade more slowly, as I don't want to become a liquidity withdrawal machine. The word "fairness" sounds grand, but in practice, it boils down to: whoever has the power to queue, who is the one placing the order.
