Why does the speaker of a modest proposal think the food he proposes is very proper for the landlords?

In "A Modest Proposal," the speaker suggests that consuming the children of the poor would be a suitable solution to poverty and overpopulation in Ireland. He argues that it would benefit landlords by providing them with a source of cheap, nutritious food, alleviating their financial burdens while also reducing the number of dependent poor. The satire highlights the callousness of the wealthy, suggesting that their indifference to the suffering of the impoverished is akin to viewing them merely as commodities. Through this extreme suggestion, the speaker critiques the dehumanizing attitudes of the landlords towards the lower classes.
