If a given population is expanding and buying up a particular sort of real estate, my first guess is that they have a comparative advantage at making use of that sort of real estate and are more-or-less rationally taking advantage of that. People using comparative advantages to produce gains from trade is one of the cornerstones of the modern economy, from which everyone involved tends to benefit. Are you advocating taking resources away from those who could demonstrably make better use of them, for ideological reasons, and if so under what conditions?
So suppose group A has a rule of never taking loans from outside, and never selling capital or real estate to outside. It seems like they should be able to slowly grow in size even if they are very inefficient, no?
Essentially the problem is if the Amish discount the future less than we do, they win the future.
So maybe the problem is that we're discounting the future more than is morally appropriate? Can we fix that?
I was browsing my RSS feed, as one does, and came across a New York Times article, "A Village With the Numbers, Not the Image, of the Poorest Place", about the Satmar Hasidic Jews of Kiryas Joel (NY).
Their interest lies in their extraordinarily high birthrate & population growth, and their poverty - which are connected. From the article:
From Wikipedia:
Robin Hanson has argued that uploaded/emulated minds will establish a new Malthusian/Darwinian equilibrium in "IF UPLOADS COME FIRST: The crack of a future dawn" - an equilibrium in comparison to which our own economy will look like a delusive dreamtime of impossibly unfit and libertine behavior. The demographic transition will not last forever. But despite our own distaste for countless lives living at near-subsistence rather than our own extreme per-capita wealth (see the Repugnant Conclusion), those many lives will be happy ones (even amidst disaster).
So. Are the inhabitants of Kiryas Joel unhappy?
