讲个笑话，这是19世纪英国工业革命时期劳动者饮食水平的地板：

“The most pessimistic report about the amount and the quality of food consumed in the industrial towns, is to be found in the short book “The Moral and Physical Condition of the Working Classes employed in the Cotton Manufacture in Manchester” (1832) by Dr. Francis Kay. The book served as a source for Engels’ statements about the horrible conditions of the working classes. Dr. Kay worked as a doctor in Manchester for a few years, and was later a well-known politician of liberal leanings, and very interested in improving the education of the lower classes. He gives us a number of insulting descriptions about the life and habits of the workers in Manchester, particularly the Irish. The living and sanitary conditions are disgusting. According to his data, the operative works in the factory from 6 to 8 a.m., returns home for a breakfast of tea or coffee with a little bread, for lunch he has a mess of potatoes with melted lard or butter and sometimes pieces of fat bacon; for supper he has tea and a little bread sometimes with oatcakes. Those with better incomes may eat a little animal food, but no more than three times in the week. It seems to be impossible that a man could do hard physical labour on so little food. ”

【简单翻译】关于工业城镇食品消费数量和质量的最悲观的报告，可以参见弗朗西斯·凯伊博士（Dr. Francis Kay）1832年出版 的小册子《曼彻斯特棉纺厂工人的道德和身体状况》 。这本书成为恩格斯关于工人阶级恶劣条件的论述的来源。凯伊博士曾在曼彻斯特当过几年医生，后来成为著名的自由主义政治家，非常热衷于改善下层阶级的教育水平。他对曼彻斯特工人，尤其是爱尔兰工人的生活和习惯进行了一系列非常悲观的描述。他们的生活和卫生条件听起来令人作呕。根据他的资料，工人早上6点到8点在工厂工作，早餐是茶或咖啡，配上一点面包；午餐是土豆泥、融化的猪油或黄油，有时还会吃几片肥熏肉；晚餐是茶和一点面包，有时还会配上燕麦饼。收入较高的人或许会吃一点肉食，但一周最多不超过三次。一个人靠这么少的食物，似乎不可能从事繁重的体力劳动。

↑ “早上喝茶喝咖啡加面包，中午吃土豆浇猪油/黄油偶尔配点咸肉，晚餐喝茶和一点面包，每周吃肉最多不超过三次”——————这是什么？这是英国工人活的最差的情况！是被英国自家的改良主义者拿来控诉社会不公、屁民生活凄惨的证据！是被恩格斯他老人家拿来批判资本主义时举的例子！[泪奔]
