MEV began as Miner Extractable Value, but a lot of people are adopting Maximum so that they can keep the same acronym for proof of stake. They typically don't have the on-chain analysis or skill to reorder the transactions in the highest extractable way, so people bid for these opportunities through side channels they signal the miner to do (off-chain) based on the mempool (backlog) of transactions. Miners profit from this activity and in some cases these profits exceed the 2ETH per block issuance. The class analogy is strained and doesn't fit at all. These are only possible because Ethereum has a rich application layer (and if anyone is 'working class' it's the users, devs and dapps on the chain). But these profits more than made up for any offset in EIP1559 losses.
