We have other forms of socialism too...

Police, some TV and radio stations, communications systems, fire department, highway and transportation systems, public schools, armed forces, post offices, municipal, provincial, and national government structures and justice system, railway systems, and so on and so on. Every modern society depends to a large extent on socialism.

Socialism is what you use to do things that aren't inherently profit-driven or profitable but STILL have to be done anyway to keep society functioning at all! ;-)
