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?

Not really. Without some edge over other potential uses for that land, they'd eventually overstretch and collapse (if they loan to each other, even in hopeless cases), or reach an equilibrium where they're losing land to things like property taxes, probate, and adverse possession as fast as they're buying it up.
I can imagine a future scenario where Amish people own all arable land on Earth and everybody else lives in skyscrapers, arcologies, space stations, or...
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?
