@62: Actually, this isn't true. Capitalism and competitive systems prey on insecurities and drives for power that people experience, and these feelings are more prevalent in the first place in times and places when people are socialized to experience them. Middle-class people who are raised in meritocratic capitalist families and schools (public state schools in general) that ignore the material differences between people are presumably much more likely to see this Darwinistic sense of competition as "natural" than, say, people who are consistently on the short end of the stick, or raised in more communitarian environments. I would suggest reading some Kropotkin, such as Mutual Aid, the basic premise of which is that life is inherently social and interdependent, rather than cutthroat and competitive. Psychologically, this makes sense as well.
For a quick read, I would also really recommend reading this section in Gelderloos's Anarchy Works: http://theanarchistlibrary.org/HTML/Pete…
A basic observation here is that what holds together an anti-oppressive community on any front (gender, race, etc.) is an intentional commitment to egalitarianism/equality/non-oppression. Talk about shit, set intentions, and these intentions become remarkably more workable than before a group of people ever mentioned them.
Feel free to explore elsewhere in Gelderloos's work as well.
