So writes Mark Bittman in the NYTimes.
Logically he's saying we need higher food prices, in order to attract more people to farming.
That's not the way he's going. Instead, while he acknowledges beginning farmer programs which assist people to buy land, he suggests that we forgive student loans for people who farm for 10 years. Needless to say I don't like the idea--it's bureaucratically messy and, I suspect, economically inefficient.
