The American economist James Yunker detailed a model where social ownership of the means of production is achieved the same way private ownership is achieved in modern capitalism through the shareholder system that separates management functions from ownership. Yunker posits that social ownership can be achieved by having a public body, designated the Bureau of Public Ownership (BPO), owning the shares of publicly listed firms without affecting market-based allocation of capital inputs. Yunker termed this model pragmatic market socialism because it does not require massive changes to society and would leave the existing management system intact, and would be at least as efficient as modern-day capitalism while providing superior social outcomes as public ownership of large and established enterprises would enable profits to be distributed among the entire population in a social dividend rather than going largely to a class of inheriting rentiers.[55]
