See, this is part of why I’m not a communist. Not all value derives from labor, some is naturally occuring.
The other sticking point is the inherent value of labor. In communist theory (as I understand it) the value of the final product is equal to the value of the labor required to produce it. But this means that if the product is, well, crap, then the labor put into it is without much value. That’s a no-sell for me. You can say that the value of the labor was wasted, but to say it doesn’t exist? I can’t agree to that proposition.
