For decades, antitrust rules have been weakened, leading to an enormous decline in diversified agriculture. In recent years, USDA and DOJ joined to hold hearings around the country. A large number of farmers lined up to speak at the first hearing in Ankeny Iowa, but the hearing was cut off leaving hundreds of them cut off from the process. Over all a huge number of comments were generated in favor of reforms. While a few reforms were made, many of the main ones were not implemented in any adequate way, as discussed here: "Eleven proposed GIPSA rules did not make the final cut," http://agpolicy.org/weekcol/595.html.
