Socialism originally refer to the “dictatorship of the proletariat” which means “government by the working class” before the Liberal redefinition of dictatorship. In this case, the pursue of profit and privatization can be acceptable on some context, material condition, or economic stage. If the private sector has not been taken over by a few property owning elites that rigged market competition and dictate that the people should be punished and rewarded according to their services to the few free riding Capitalists, then the private sector could be tolerated in the early stage of economic development to Socialism. Nationalization should occur in the later stage of Capitalism when the economy became dominanted by an uncompetitive oligarch or monopoly.

Information about Nicaragua is rather hard to find on English internet, all I’ve been able to find on nationalization is that they expropriated the Somoza dictatorship and land held by the contras. Then they did land reform, encouraging people to make cooperatives. By 1991 40% of their GDP was from nationalized industry. Then the neoliberals took power for a few years and tried to privatize some things. After that the Sandinistas regained power, and apparently all we know about the last twenty years is “ebil commies rigging elections.” Im not sure where I found the solid half figure. I swear I found it in my research a couple months ago.
