When asked why he robbed banks, Willie Sutton answered, “because that is where the money is.” It is easy to see why a group consisting mainly of bank robbers would be found mainly around banks.
What’s more interesting though is how a group that somehow winds up everywhere would originate from the same place—especially when they aren’t acting as a group but rather individually. It would be comparable to all the bank robbers in the country coming from the same town. We’d have to wonder what was in the drinking water.
Take the cities of Philadelphia, San Pedro de Macoris in the Dominican Republic, and the arid, sparsley populated area of Extremadura in western Spain. These three locations would have a profound effect in three distinct areas of human accomplishments based simply on the unusually high concentration of its citizens involved in those endeavors.<
