who or what owns the means of production in a socialist economy
Socialist economics The ownership of the means of production varies in different socialist theories. It can either be based on public ownership by a state apparatus; direct ownership by the users of the productive property through worker cooperative; or commonly owned by all of society with management and control delegated to those who operate/use the means of production.
Capitalism Historically, capitalism has an ability to promote economic growth as measured by gross domestic product (GDP), capacity utilization or standard of living. This argument was central, for example, to Adam Smith's advocacy of letting a free market control production and price and allocate resources. Many theorists have noted that this increase in global GDP over time coincides with the emergence of the modern world capitalist system.[86][87]
