The listener letter last week asked about the the three "red dots" that are used to identify liquor stores in South Carolina. Turns out that this kind of "shibboleth" is a way of identifying and discriminating, in ways that can be useful, or harmful.
ERRATUM: MJ writes to point out that if the economist could really count, he would have miscounted the number of sheep, adding one, because he counted the dog. That's fine. But then why did the shepherd agree that the number of sheep was correct? It should have been one over. It's okay that TWEJ's are not funny, that comes with the territory. But in this case there is a logical problem. My mistake, and thanks, MJ!
