" In my own passage out of the left nearly 20 years ago, it occurred to me that my revolutionary comrades never addressed to themselves what should be the obvious questions for social reformers: “What makes a society work?” “What will make this society work?” In all the socialist literature I had read, there was hardly a chapter devoted to the creation of wealth, the problem of getting people to work or to behave in a civilized manner. Socialist theory was exclusively addressed to the conquest of power and the division of wealth that someone else had created. Was it any surprise that socialist societies had broken world records in making their inhabitants poor? "
