Explanation:

In the foreground, we can see that the text "A Modest Proposal" has a satyr character, in which Jonathan Swift addresses points on how to solve the problem of poverty in Ireland. According to the author, children born to poor families generate even more expenses for their parents and their kingdom, being the most appropriate solution for such a situation the slaughter of these children so that they serve as food for rich people. Thus, the implicit meaning of the text is that eating babies is such a good proposition to improve the kingdom's economy that no one will disagree.  Since these children would end up starving or sick, or could even enter the world of crime, by serving as "food" to landowners and merchants, they would no longer be a burden to their parents and kingdom, and would be beneficial to all.
