I'm not sure they're saying that nothing can be done, just that increased healthcare and therapy is unlikely to make a large impact. Addressing the actual problems driving them to suicide could reduce the numbers. They have some programs about USDA aid, lawyers, accountants, etc that farmers can use to address some of the issues.
> increased healthcare and therapy is unlikely to make a large impact
In places where there is a lack of healthcare and therapy, increasing it seems very likely to make a significant impact. If they are against increasing it, then don't complain about the lack of healthcare.
"increasing it seems very likely to make a significant impact."
Have you been reading the same information here? There are other factors specific to rural areas that would need to be overcome for healthcare and therapy to have an impact on suicide.
