What Is the Primary Incentive for a Miner to Prioritize High-Fee Transactions?

The primary incentive is economic self-interest and profit maximization. Transaction fees are an additional reward on top of the block subsidy (newly minted coins).

By including transactions that offer the highest fees per unit of block space, miners maximize the total reward they receive for successfully mining a block. This competitive behavior drives the fee market and ensures network security.
