  In this paper we use a close connection between the coupled wire construction
(CWC) of Abelian quantum Hall states and the theory of composite bosons to
extract the Laughlin wave function and the hydrodynamic effective theory in the
bulk, including the Wen-Zee topological action, directly from the CWC. We show
how rotational invariance can be recovered by fine-tuning the interactions. A
simple recipe is also given to construct general Abelian quantum Hall states
desceibed by the multi-component Wen-Zee action.
