To understand the failings of existing farm programs, it’s important to understand the roots of the current farm crisis. At the heart of the problem is money—how much there is and how much it costs to borrow.
A farmer is a debtor almost by definition. In my own state, it’s not unusual for a wheat farmer with 1,000 acres to owe several hundred thousand dollars for land and machinery.

Today, we want empathy, not inspiration.

In 1337, Petrarch began work on his rambling writing De Viris Illustribus--On Famous Men, highlighting the virtus (or virtue) of classical heroes. Petrarch celebrated their greatness in conquering fortune and rising to the top. This was the biographical tradition which Niccolo Machiavelli turned on
