See, I don't know if that's exactly true. What have you read about other countries, in terms of land division? In Mexico for example, you might not have as much economic opportunity, but if one's family has a bit of land, does the ownership of it at least exist more firmly in the hands of the owners? Is the government after you for property tax, and to get hooked up to what they consider essential utilities?
Like for example, I could buy a little plot of land in america, with no house perhaps. But if I were to live on it with a tent or a trailer, without hooking myself up to the grid, or to water, then it seems like american society might have a huge issue with that, perhaps on some basis that I'm either not 'paying in' enough, or it's not good to them aesthetically.
So what about other countries, in this world. It can't possibly all be the same. Like in some of those countries that I saw Anthony Bourdain travel in, out toward Southeast Asia. Well it kind of seems like a large tax structure / utility operation did not really move into such places, perhaps, and so that seems to free the common populace to get a closer relationship to the land, on some level.
So maybe also, then, it might not even really be totally about the 'rich,' to some extent, and not to challenge your whole point - but in part it might be about the material structure. The material structure contains us all. They may not want you living in a tent on a piece of land, in part because that doesn't pay for the 'material structure' that is the school, or the road, or the military, or government. See what I mean?
As for your point 'very long time,' I'm not even so sure about that. In my reading of the gospels, I actually think the poor masses seemed to have more rights in the 1st century than they might have now, in our homeless epidemic. And it also seems like the apostles had less trouble crossing borders in that section of the ancient world, than people seem to have now. But of course, the roman world also had actual frontiers, at that time.
