Final answer:
Hentoff predicts that the public, particularly older individuals, will vehemently oppose Callahan's proposal, likely due to concerns over healthcare or retirement resource allocation. Elderly activism in politics has historically shown that such demographics will advocate strongly for their interests, as in the support for the Townsend Recovery Plan or in protests to safeguard Medicare entitlements.
Step-by-step explanation:
Hentoff predicts that as more individuals survive into old age, public opinion will be strongly against Callahan's proposal, which is likely a reference to limiting healthcare or resources for the elderly. This prediction is based on historical and contemporary examples where senior citizens have actively advocated for their rights and interests. For instance, the Townsend Recovery Plan had a strong following among older Americans during the 1930s, suggesting that similar proposals offering support to the elderly could garner significant support. Moreover, current trends indicate that older individuals are more likely to be engaged in political activism, as they regularly vote and are willing to protest to protect entitlement programs like Medicare.
Opposition to proposals that are perceived to threaten retirement income or healthcare can become politically charged, as seen in the past with rallies and protests against policy changes affecting older populations. Additionally, if the elderly perceive a proposal as putting their financial security at risk, such as proposals tied to stock market investments, the opposition could be fierce, given the high stakes involved.
