==what do make of this?== 
 There is a valid article somewhere in there.  
 The problem, as so often, is that the article makes a half-assed attempt to , but after a couple of paragraph kind of throws up its hand and goes on talking about the United States exclusively. 

 This need not be a problem, you can write a valid article all about the United States, just make this explicit in the title and lead. 

 "Family farm (United States)" would seem like a good title.  
 I see at least three pages waiting to be pulled from the wall of text I found here 
 *A "global" article, family farming, written based on whatever the UN has to say about "family farming" with a global and contemporary scope 
 *A historical article focussing on landed estate (Hof (estate)) in Germanic Europe, and the development vs. manoralism in the medieval period, vs. industrialisation in the modern period, and its influence in colonialism, emigration to the New World, the Russian Empire and African colonies 
 *Family farm (United States), which can go into glorious detail about all  historical, political and economic detail it likes 
 Of course there can always be other regional spin-off pages from the "global" page, e.g. on Brazil.
