evidence: Former governor of South Carolina Nikki Haley has maintained throughout her campaign that she’s open to raising the retirement age for younger people. [...] Haley’s opponent, Florida Gov. Ron DeSantis, vehemently disagreed with her on raising the retirement age, pointing out that retirees have been paying into Social Security their whole lives and deserve to receive it. [...] One big reason why DeSantis doesn’t agree with Haley about raising the retirement age is life expectancy. Haley insists that life expectancy is increasing, so raising the retirement age just makes sense. But DeSantis says that this isn’t true: life expectancy has decreased in the past five years.
