How Do Small Farms Survive?

Here's the piece from which I stole the heading:
The answer: renting out a minihouse through Airbnb

Another piece in the media suggesting comfort animals, as in those with big brown eyes, aka "cows", is the answer.

The real answers, of course, are:

1. off-farm income, as has been the case for decades.
2. drawing down capital (i.e., the value of land and buildings)   (My mother used to fuss about farmers who would be better off selling out and investing the proceeds in bonds.)
