What objection to the proposal does the speaker think readers might raise? How does he answer that objection?

The speaker proposes that “out of the one hundred and twenty thousand children from poor families born annually, twenty thousand should be kept for breed and the remaining one hundred thousand sold as food to persons of quality of fortune, at one year of age.” He does not think that his proposal will raise many concerns among the multitudes, unless if it could be argued that such measures would greatly reduce the population of Ireland. To this singular objection, he accepts that indeed, the proposal aims to reduce the population of people in the kingdom. He further states that all other proposals, previously given, have failed to work. He even lists some of these proposals such as “taxing of absentees at five shillings a pound, promoting the use of local products, love for the country, and fostering of a spirit of patriotism among all people to work towards the general good of the country.” He dismisses all these measures by saying that “let no man talk to me of these and the like expedients until he hath at least some glimpse of hope, that there will ever be some hearty and sincere attempt to put them into practice”. He states that his proposal “offers a wholly new, solid, real, and inexpensive” alternative to the many “visionary” proposals that have failed to take off in the past.
In support of his proposal, the speaker reminds objectors of two points worthy of their consideration. One, how to provide for one hundred thousand poor mouths, and two, the thoughts of poor parents on such a proposal as he has presented—whether they wouldn’t have preferred to themselves be sold for food at one year of age, instead of living to endure “such a perpetual scene of misfortunes.”
The writer makes heavy use of satire to draw the reader’s attention to problems faced by the society of Ireland at the time.
