How does Swift propose to make children sound useful members of the commonwealth?

In "A Modest Proposal," Jonathan Swift suggests that by raising children as a source of economic benefit, they can become useful members of society. He sarcastically proposes that impoverished parents sell their children as food to the wealthy, thereby reducing poverty and providing a new source of income. This shocking suggestion serves to highlight the dehumanization of the poor and critiques the indifference of society towards the suffering of the lower classes. Ultimately, Swift uses this extreme satire to urge a more humane approach to solving social issues.
