When personal profit is the prime motivator in society then technological profligacy, over-consumption and over-population are bound to result. A plethora of things. This all relies on division of labour: an army of others making and providing what I consume. If I were only allowed to consume what I can grow and make myself then things would be very different. Spiritual work has such self-sufficiency at its core. As my teacher used to say: I can't do the work for you, and if I could, I wouldn't.
