In societies under the rule of exploiting classes,there are various kinds of mental workers. 在剥削阶级统治的社会里，有各种各样的脑力劳动者。
In a socialist society,the mental workers trained by the working class itself are different from intellectuals in any exploitative society past or present. 在社会主义社会里，工人阶级自己培养的脑力劳动者，与历史上的剥削社会中的知识分子不同了。
