I can speak to personally witnessing most of the ag families I've known in the last 50 years selling out to large ag conglomerates because the family ran out of generations willing to spend their entire life skirting bankruptcy. If the claim that this is predominantly ag workers and not owners outright committing suicide is accurate I'd probably counter something along the lines of in generations past before big ag strangled the life out of smallholding farmers most of those workers would very likely have been farm owners.
