I find Socialism quite a broad name and depending on which shade we look at it through, it can mean collectivism, absence of a free market, centralized decision making, bureaucracy, and the potential for an authoritarian administration.

A Welfare State on the other hand covers the things you mentioned, and has fewer negative connotations. I'm saying this here because the state providing a minimum welfare guarantee to its citizens should be an unquestionably accepted idea, but the confusion with socialism often undermines it.
