Much written on this, including by Hayek, who makes the point that socialists win over intellectuals and public opinion by boldly promising utopia. Practical people know utopia isn't possible, and so lose the battle of public opinion, which intellectuals enjoy winning.
中文: 关于这一点,包括哈耶克,他指出,社会主义者通过大胆承诺的乌托邦,赢得了知识分子和公众舆论的争夺。务实的人知道乌托邦是不可能的,因此输掉了舆论之争,而知识分子们喜欢赢得舆论。
