How long would it take to establish shareholder socialism?

This paper develops a formal framework for the establishment and expansion of a Sovereign Wealth Fund (SWF) from the perspective of Shareholder Socialism. After reviewing the heterogeneous origins and financing arrangements of existing SWFs, we present a dynamic model that characterizes feasible pathways through which advanced economies can build a large-scale public equity fund without relying on natural resource revenues or foreign-exchange reserves. To evaluate the time required to reach target fund-to-GDP ratios under plausible scenarios, we use Monte Carlo simulations that account for return uncertainty. The results indicate that a sizeable public wealth fund can be accumulated within twenty to thirty years.
