"老害殺害計画," literally translated as "The Master Plan to Kill the Old Guards," was the title of the book promised by a Tokyo-based right-wing publisher a year ago in May 25, 2022 to now worldly famous (or infamous) professor #YusukeNarita, @YaleEconomics Assistant Professor.
Although Narita wrote in his email response to @nytimes that his comments "primarily concerned" the "tycoons" who remain in control of various industries, he did not make the distinction when aging in rural villages was being discussed. He proposed the same solution.
So it is safe to assume that his "only solution" applies not only to the "old guards" but also to the common elderly who "may become harm to society," which is what the wording "老害" stands for; a harm brought on to the society by gerontocracy. So how will distinction be made?
