With the collapse of tourism in Hawaii, relatives on the Big Island tell us they and many others increasingly are growing their own food, as well as fishing and hunting (like for wild pig.) There are few jobs there now since tourism dropped off sharply as a result of the recession. It’s fend for yourself, tilting towards a barter economy, as in I’ll swap you fresh mangoes for some of that fish you just caught.
I bet we see much more of this. If such economies grow, then governments becomes less and less important. Hmmm.
