If I try breeding chickens and some of them stop laying eggs, should I abandon the whole endeavor and start buying my chickens from the local supermarket because some chicken are dicking around?
All national efforts are going to have some waste, it's inevitable and I think we can more than comfortably afford it. Our job should not be to scrutinize every detail in order to minimize waste (of course we should be doing that as well) but rather to make sure that every wheat seed and every chicken have all they need in order to fully develop themselves to the best of their abilities.
