Final answer:
Swift expresses frustration with past futile reform attempts and presents his new proposal as practical, cost-effective, and without risk of offending England.
Step-by-step explanation:
Jonathan Swift, in his satirical essay “A Modest Proposal,” conveys a sense of exasperation due to his previous futile attempts at suggesting reforms through “vain, idle, visionary thoughts.” He presents his new proposal as something tangible, practical, and attainable without incurring any risk of offending England. By stating that he has “been wearied out for many years” in proposing changes without success, Swift emphasizes that his current proposal is not only innovative (“wholly new”) but also realistic (“solid and real”), inexpensive, and within “our own power” to implement.
