The head female of a paper-wasp nest allows others to occupy space in her home—so long as they help raise her offspring. The labor market is, however, elastic: if other nests nearby have childcare needs, she maintains a lower work requirement from her “helper” wasps.

Corporations, wrote Edward Coke in a 1613 legal decision, “have no souls,” for they are “invisible, immortal, and resteth only in intendment and consideration of the law.” A corporate body, Coke argued, can’t “do fealty, for an invisible body cannot be in person, nor can swear.”

Economist Frédéric Bastiat published a parodic open letter to French parliament in 1845 that imagined the national lighting industry lobbying for a law to black out all windows in response to the “ruinous competition” of the sun, which was “flooding the domestic market.” “Be logical,” the letter concludes, “for as long as you ban, as you do, foreign coal, iron, wheat, and textiles, in proportion as their price approaches zero, how inconsistent it would be to admit the light of the sun, whose price is zero all day long!”
