As I've argued before on this blog, the core challenge for every modern society—regardless of its political structure—is how to get large numbers of genetically-unrelated strangers to cooperate with one another in complex enterprises for long periods of time. In order to achieve this seemingly miraculous feat, as I've pointed out, states tend to rely on some mix of three basic motivators: coercion (Max Weber's "organized violence"), economic self-interest, and voluntary altruism (a.k.a. morality).
A key objection to capitalism and market society from their inception has been that they rely too heavily on the second of these three motives, at the expense of the third. As Marx and Engels put it, capitalism had reduced human relations to nothing but "callous 'cash payment.'" Thomas Carlyle famously made the same critique, warning against the "cash nexus" becoming the sole basis of human society.
