They will take only those who are willing. In the long run, even "democratic" capitalism is merely a slow death by starvation (in contrast to dictatorship which would amount to stoning) due to the same blindness. Then again, and if nothing else, eventually the end of the universe, whatever the shape it will have, will sort it out either way. In any case, neither the unsustainable habits of dinosaurs, not even the meteorite, were able to extinguish all reptiles. That is to say, it's safe to assume that humanity survives in some shape and form, and, in such case, it's clear that those archaic transactional modes of thinking I mentioned at the beginning are bound to disappear one way or another.
