“…It was in this vein that the seventeenth-century political economist, William Petyt, spoke of labor as “capital material …raw and undigested…committed into the hands of supreme authority, in whose prudence and disposition it is to improve, manage, and fashion it to more or less advantage.” 3 Unskilled laborers have featured more prominently in literature on mobs, unrest, and disputes in pre-industrial London than in economic analysis (George 1965, p. 124; Harrison 1986; Landes 1987; Gilboy 1934). Although some studies suggest laborers might have more complex relationships with their employers (Woodward 1995; Yamamoto 2004; Schwarz 2007), economic historians have generally agreed that more structured approaches to hiring arose later (Clark 1984, 1994), when firms eventually “rejected the market…to secure a reliable and productive labor force” (Huberman 1996, p. 6).…”
