This article invokes the theory of innovative enterprise to analyse the relation between value creation and value extraction in the evolution of the US economy. Beginning with a managerial, as distinct from financial, explanation for the separation of ownership and control in the US corporation a century ago, I focus on why and how a "retain-and-reinvest" corporate resource-allocation regime has been a necessary condition for innovative enterprise in the US economy. On that basis, I demonstrate that the ideology that the economy will achieve superior performance if business enterprises "maximise shareholder value" (MSV) is a theory of value extraction that promotes a "downsize-and-distribute" allocation regime and that results in employment instability and income inequity. Like the neoclassical theory of the market economy in which it is rooted, MSV lacks a theory of innovative enterprise, and hence cannot explain how, through the investment strategies and organisational structures of its major business enterprises, a national economy might achieve stable and equitable economic growth.
