I enjoyed Karen Palasek’s “Free Market Minute” on why some forms of “self-sufficiency” are not only uncomfortable but economically undesireable.

But I do have to say it’s not the Robinson Crusoes I worry about. Robinson made a bad choice, ended up paying for it, and learned from the experience. It’s the wrongheaded Henry David Thoreau-types who volunteer for the experiment, draw the wrong conclusions, write books about it, and get quoted as authoritative for the rest of us … these I worry about.
