Farmers are the worst. Pleading poverty with a brand new discovery on the drive. Some of the worst lash ups I ever see are on farms.
I think it depends on the type of farmer and farm. Hill farmers near me have never been rich, just getting by with sheep and a few cows. A bad year lambing can really hurt them, non had rangies, most ran very old cars with everything going back into the farm. It’s a very hard, 365 days a year, long days in all weathers, life!
