I'm not terribly impressed with their central thesis:
Capitalists and corporations, we argue, are driven not to maximize profit, but to ‘beat the average’ and increase their differential power. In this approach, the redistribution of income and assets is not a ‘societal’ side effect of the economy, but the central conflict that propels modern capitalism. And the main weapon in this struggle, we claim, is not investment and growth, but what the American political economist Thorstein Veblen called ‘strategic sabotage’ – the restrictions, limitations, hazards and pains that capitalists impose on the rest of society in order to sustain and augment their differential power.Capitalists and corporations are motivated by both. Given that capitalist operations are now coming up against the resource limits of a finite planet, they are driven more by the second motivation which essentially constitutes power and control.
However, I am really impressed with, and amused by, their deconstruction and satire of current efforts by capitalists, especially "enlightened capitalists" to defend their system.
