What is the cumulative effect of Swift presenting the six advantages one after another in "A Modest Proposal"?

Clearly this part of this hilarious and grimly satirical
essay is part of Swift's design of creating a speaker who is above all trying to present
himself as reasonable and logical in the way that he proposes a horrendous idea. If you
read through the six advantages to turning Irish children into a form of human cattle
for consumption, one is struck by the emphasis on reason and logic in the arguments that
the speaker uses. All would benefit from adopting this measure, from the English
landlords to the poor themselves, according to the chain of
argument.

Of course, such emphasis on an appearance of
logic and reason only serves to augment the true horror and disgust that Swift is trying
to produce. In reality, the poor would suffer even more than they were during the famine
in the first place. Thus it is that Swift shows how adopting such a logical, reasonable
and statistical view of humanity can result in converting ourselves into monsters whilst
also protesting against the inaction of the English in doing nothing to alleviate the
horrendous conditions of the Irish famine.
