Q: How do we reconcile on the one hand farmers by trade leaving and wannabe farmers wanting to join a farm life?
A: "people who want to do x and have money can end up in a better spot than people who inherited x and have less money?"
Is that not a valid criticism?
But obviously people aren't such rational actors, and farmers have emotional attachments to their farms, the rural areas they grew up in, etc. And so they keep trying to make the old model work, increase their debt loads and hope things will turn around until its too late.
I don't want to set up a straw man here, but a hypothetical analyst could look at this trend and think something special is happening with farming (as mc32 put: "[thinking] that they have a better farming plan or better farming insight over generational farmers") — picture a cover story with the headline "farming is back", now picture a less upmarket story titled "15 reasons to be a farmer (ear of corn emoji)! You won't BELIEVE number 12!".
Whereas it's an iteration of the eternal "strike gold, open a boutique" story.
