Money is immaterial?!? As Homer Simpson once said (to his brain): "money can be exchanged for goods and services" - like healthcare, education, important stuff....
Is your idiocy also material? Maybe you should have it removed.
EDIT: Joking aside, the knowledge how to work a job is valuable, but immaterial. Undernourishment is often a matter of lack of the knowledge how to extract resources from the environment. Of course a lot of wealth is attained by theft. But what's theft of ideas, are ideas material wealth? Sure I'm talking semantics, I try to understand you. I don't assume you are totally wrong, I just tend to assume that my language faculty is sufficient to follow involved arguments. Often erroneously, but therefor I'm skeptic of others as well. I suppose the distinction between material and immaterial is largely immaterial, and the difference between abstract and concrete best hidden from conversation.
