恩格斯在1872年写过一本经典著作——《论住宅问题》。他针对当时欧洲大城市“住宅缺乏”的社会问题作了研究,在德国莱比锡《人民国家报》上接连发表了三篇文章,结集出版了这本书。时隔139年后重读,大有收获。恩格斯指出:“今天所说的住宅缺乏现象,是指本来就很恶劣的工人的居住条件因为人口的突然涌进大城市而特别尖锐化;房租大幅度提高,每一所房屋里的住户愈加拥挤,有些人简直无法找到住所。这种住宅缺乏现象之所以引起人们的议论纷纷,只是因为它不只局限于工人阶级,而且也伤害到小资产阶级。” Engels wrote a classic book in 1872 - “On the issue of housing.” He studied the social problems of the “lack of housing” in the big European cities at that time. He published three articles in succession on the People’s Daily in Leipzig, Germany, and compiled and published this book. Reread after 139 years, great achievement. Engels pointed out: “Today’s lack of housing means that the living conditions of already poor workers have been particularly acute because of the sudden influx of people into the big cities; the substantial increase in rents and the increase in the number of households in every house Crowded, and some people simply can not find shelter, the reason why this lack of housing aroused people’s discussion, only because it is not limited to the working class, but also to the petty bourgeoisie. ”
