In a civilized society it is indeed not so much the greater knowledge that the individual can acquire, as the greater benefit he receives from the knowledge posssessed by others, which is the cause of his ability to pursue an infinitely wider range of ends than merely the satisfaction of his most pressing physical needs. Indeed, a ‘civilized’ individual may be very ignorant, more ignorant than many a savage, and yet greatly benefit from the civilization in which he lives.
— Friedrich von Hayek
Yes a Green or an outright socialist or a Keynesian can be as ignorant as a savage about the foundation of our comfortable way of life and still enjoy it while they try to destroy it. Natural selection has ceased to work.
