I propose the following observation: a society which is not based on manual labor is a society in which men are held in contempt. Allow me to explain. By “based on manual labor”, I mean that the majority of people make their livelihood by physical labor, rather than the service or information manipulation professions. By “men are held in contempt”, I mean that masculine virtues are not honored by popular opinion or culture, and the majority of men are regarded as losers.
Why do I claim this? It’s biology. Men and women have different attributes; the average woman has much different qualifications than the average man. (See, for example, Taking Sex Differences Seriously by Rhoads, The Essential Difference by Baron-Cohen, and Male, Female by Geary on the innate cognitive differences between the sexes.) The differences may be summed up as follows: men are physically superior to women, but women are mentally superior to men.
