Yes, the theme of ‘everyone else does everything wrong’.
They farm too intensively, they overgraze, they don’t lovingly handfeed their 19 year old ewes bread and bury them in the field they loved, they don’t bring up their children ‘running wild and free on the land’ (I did snigger to myself when Raynor says in TSP that their daughter was cutting her travels short for a PR job in London, which she clearly thinks is not at all rock’ roll), they’re not properly in love after 30 years together like her and Moth, or they marry staid farmers rather than blond eco-warriors, they walk the SWCP on a schedule unlike her and Moth, they put extensions on their houses rather than ‘lovingly restoring’ ancient farmhouses (the snide remarks about second home owners hit a bit ironically in view of the French property), or they work in the City and have soft hands and designer sunglasses rather than working on the land.
And actually, they shuffle meekly into council accommodation and get jobs, rather than doing the free-spirited thing and walking for several hundred miles to attune to nature.
