A true reversal

I think a lot about sustainable farming, and how much I want to grow most of the food my family consumes. I realized last night that 80 years ago, you had to be pretty wealthy to consider not doing subsistence farming to stay alive. But in that time frame, America has changed so much that you have to be quite wealthy in order to realistically consider doing subsistence/sustainable farming today. My, how times have changed! And I don't think necessarily for the better.
