Answer:
In A Modest Proposal, Jonathan Swift´s suggestion that the Irish should eat their children as a solution to overpopulation and starvation functions as satire because it´s meant to criticize the treatment that the British government had had over the growing famine in Ireland.
Step-by-step explanation:
Swift´s "A Modest Proposal" was a pamphlet published in 1729. His explanation about how, if poor tenants could use their children to get money, they would be able to pay their landlords, is a critic of how British landlords had been part of the problem by evicting people after seizing their corn and cattle. The entire excerpt treats children like cattle, implying that they can even become an asset of the national economy and feed the rich. And poor parents will not only get money but also would be eventually be relieved from the cost of maintaining their children, which means that children are just like any other commodity, not a human being that is loved.
