I am atheist, which is an absence of religion. I do however have a deep appreciation for the arts and sciences, and I have a vision for what the world could and should be like. We don’t have to have homeless people. We don’t have to have hungry people or poverty. The existence of this suffering is a choice that the capitalists make in the pursuit of power.
The egregiously exploitative flavor of capitalism that exists today is a relatively recent development. I don’t think it’s intrinsic to humanity at all; humanity has been communist for most of our existence. Also, capitalism has a specific meaning; it means the means of production can be privately owned, and that owner gets to decide how many breadcrumbs to give to the workers.
