In 18 parts, Lang explores some of Smith’s central themes, including one of the book’s most famous passages, where Smith uses a wool coat worn by a very poor Scottish worker as a way to examine trade. “He asks, ‘Did you ever think of how many people need to be employed in order to make that coat?’” says Lang, whose movement “the woolen coat” names all the artisans and laborers who contributed to the garment in song:

the shepherd
the sorter of the wool
the wool-comber or carder
the dyer
the spinner
the weaver
the fuller

There are also the workers on the ship that brought in the dye and all the people who built the ship. An ordinary coat is revealed to be a kind of miracle of skilled labor and global collaboration, the product of “many thousands” of workers coming together in (selfish) harmony. Part of me wanted to run out of the theater right then and buy something … perhaps a coat… for America.
