I'd say its the billions of regulations/hoops they make farmers go through just to have a farm, and of course all the regulations/hoops they make them hop through to become even remotely profitable. It also probably has something to do with the fact that most small farms have been killed by bigger companies that make it almost impossible to make a living as a farmer anymore, unless you're lucky enough (or unlucky, depending on how you look at it) to be part of a multi-generational farm/homestead. :D
Its crazy the size of the quotas and the amount of paperwork they expect you to complete, sometimes more than once, and the costs associated with starting a small farm/homestead aren't conducive to getting new farms up and running either. These are all factors that could raise someone's stress levels so high they'd do something drastic like that.
Its shameful the way they are destroying farm life, a life that is supposed to bring peace and tranquility just adds more stress that we all don't need but our governments don't care, they just want more, more, more, and they want to pay less and less for it. I can understand why some people feel that death is the only way for their family to get ahead, but they really don't get ahead because they'll lose one of the key components to their lives when they lose their loved one to suicide.
These are, of course, just my personal opinions and everyone will have their own, some may disagree with me and that's okay. We are all entitled to opinions. :D I'm very grateful that I live in a country that lets me state my personal opinions without fear of retribution, some people aren't that blessed. :D I hope God blesses all the farmers/homesteaders out there. :D
God bless you and your family. :D Have an awesome day my fabulous friend! :D
