You need only think about the axioms under which the traditional S/D graph holds true, to realize labor likely represents a distorted market. 1) Goods are fungible (spend 5 minutes interviewing for technology and come back and try to defend this one) 2) There exists "perfect" competition (that is to say any supplier can enter or exit the market, and there's full knowledge on the marginal utility of all goods) The nature of labor muddies these waters and the world turns out to be a lot more complicated than econ 101 (notice that those axioms are almost never true regardless of market).
