The suicide rate for farmers in the U.S. is more than double that of veterans
I have family that farms in Iowa and I also worked in the agriculture  industry there for a while after leaving the military. One thing that increases the stress on the farmers is the way they avoid income taxes at all costs so they rarely save any of the profits from good years to help them float during the bad years. This is all anecdotal but I have personally talked with several farmers that would rather buy new equipment they say do not even need than pay the taxes to take the money as income. This mindset causes them to experience a huge amount of stress every season. The farmers would talk about struggling, but have a brand new semi-tractor sitting in a barn unused 10 months out of the year.
