Nothing changes until it can change. No changes happen, and no new things are created, until there is the technology and the know-how that can bring those changes about.
All lack can be abolished through knowledge and the application of technology, once that technology exists, to the abolition of lack. If the technology is lacking, know-how is needed to create it, and more know-how is needed to apply the technology to that other thing that is lacking.
But, what is lack?
Lack may be felt, or it may be imagined. It is in the realm of imagined lack that creativity becomes the protagonist. Lack can also be universal or local or individual. An egalitarian economy has to be based on a science of lack, which in turn, needs to be rooted in necessity. The social-utopian slogan “from each according to his abilities, to each according to his needs,” is, fundamentally, a question of lack.
