Why is this agreement necessary for setting the groundwork for the satire a modest proposal?

This agreement is necessary for setting the groundwork for "A Modest Proposal" because it creates a satirical tone that allows Swift to propose shocking solutions to serious problems. By feigning reasonableness and even-handedness, Swift can highlight the absurdity of the social issues he is addressing, such as poverty and overpopulation. This approach enables Swift to critique the prevailing attitudes and policies of his time in a thought-provoking and memorable way.
