I am not be a farmer, no. However you don't need to be a farmer to know you can't run any business on 7% loss. We've heard this point about losing money in dairying for decades, yet there are still dairy farmers. Have they all really been subsidising dairying out of their own pockets for all these years? It is hard to believe. I do accept there are good and bad times in any business and not to say it's easy money in the good times. Also it isn't that long ago when milk quotas were bought and sold ergo had value. A licence to lose money wouldn't have fetched much.
I worked in a business which lost money for a number of years and one by one the competitors folded and eventually, and quite sensibly, they closed down our division. We were all hanging on hoping for better times when everyone else packed in but ultimately there simply wasn't a living to be made supplying our particular sort of IT systems to the the railways, at least not whilst every station wanted a bespoke system completely different from every other.
