I'm not American and not particularly familiar with the economics of the agriculture industry there, so I don't really feel qualified to comment. I'll just point out that government actions often favour such large corporations, preventing for instance the collapse of certain banks and auto manufacturers during the GFC. I do know that farm subsidies in the US are quite extensive. If the government had decided 70 years ago that it owned all the nations farmland, and had auctioned it off to four large corporations, making it law that nobody else could own farmland, would the farmland situation would be better or worse than it is now? I'd argue for worse.
