I think the problems are not only racism, materialism and militarism but also the USE of racism, materialism and militarism by the ever-richer oligarchy to trigger the rest of us into hating people who are different from us, buying more and more stuff that is designed to fall apart quickly and thinking that the solution to every major problem is to go to war. As long as we're at each others' throats and vying with each other to have the latest stuff, we don't notice the ever-increasing wealth inequality.
