Corporate Solidarity

Paul Krugman notices class solidarity among the rich in Corporate Solidarity.

Matt Yglesias has a post about the remarkable solidarity of corporate executives, who seem to support their class interests even when their individual firms would benefit from the policies they oppose.

The ruling class always knows what is at stake. The working class has to be kept divided through racism, sexism, homophobia, consumerism, etc.

How can the working class ever become the ruling class without emulating the Capitalists by putting class interests ahead of individual interests?
