I hope that large-parcel land ownership goes into decline. I'm not sure it's all bad, though. The first post links to an article that says that Ted Turner owns a huge amount of land. I think I've heard Turner is a pretty good steward of his property, and his ownership may well be an advantage to the common good.
Here in the western US, much of the land is owned by the federal government, and conservancies are acquiring more and more land. That's a trend that I'd like to see continue.
The Bundy family of Nevada disagree.
