Every opinion based on scientific criticism I welcome. As to prejudices of so-called public opinion, to which I have never made concessions, now as aforetime the maxim of the great Florentine is mine: ―Segui il tuo corso, e lascia dir le genti.‖ [Follow your own course, and let people talk – paraphrased from Dante] --Karl Marx London July 25, 1867

性別失衡與婚姻擠壓
由於重男輕女的觀念與一胎化政策(1979-2015),中國大陸的人口結構早在1950年代起就已出現明顯的性別失衡,從而導致所謂的男性婚姻擠壓(male marriage squeeze)。有研究推估顯示,在未來的幾十年間,潛在的男性對上女性的性比例會超過1.15,換算成人數,每年男性過剩的人數會超過一百萬;而男性總過剩人數到2028年會達到三千萬,並在2043年攀至高峰的四千一百萬(Huang, 2014; Jiang, et al., 2011)。
