A big part of communism is about who owns the means of production. One way to alter this aspect of society is through cooperative economics. A state-less form of socialism (edit: democratically controlled) that’s already proven effective in small pockets of our own country (assuming US here) and around the world. One common example is Mondragon in Spain, a cooperative business and the seventh largest company in the country, that has proven its even possible for the cooperative model to reach levels of scale capable of competing in a private capitalist world.
