I read a Forbes article suggesting the end to farm programs, pointing to New Zealand as an example of that policy. One of the effects was the claim: "The effects? New Zealand retained 99 percent of its farms." That raised my contrarian hackles. In trying to find substantiation I ran across this interesting concept: "sharemilking". The farmer owns and milks the cows, and moves them from one farm to another on "Gypsy Day".
I assume by separating land ownership and cow ownership the capital requirements are lowered. I haven't heard of this before, but I suspect there may be such arrangements in the U.S., particularly as part of a succession plan.
As for the Forbes article, while it claims support from an "academic study", in fact the article, while by an academic, is more of a blog post; itself supported by only one article. I'm suspending judgment on the issue--perhaps I'll get the ambition to do more research.
