"No meaningful difference distinguishes socialism and communism — only trivial, superficial divergences that amount to distinctions without differences"
While I would agree that the question itself is outdated and sounds like a holdover from the McCarthy era...
This bit you quoted from the article, it's not inaccurate.
While, on paper, there are some small differences between the two, in practical "real world" application, they've been relatively indistinguishable from each other.
They both:
- Seek to have an expansive public sector
- Trend towards single-party rule
- Massive restrictions of (or outright abolishment of) private property
- Use top-down measures for redistribution
While the underlying philosophies are a tad different:
Marx's theory of "From each according to his ability, to each according to his need" (communism)
vs.
Henry Saint Simone's "From each according to ability, to each according to his contribution (socialism)
(Marx's theory suggests that Socialism is a stepping stone from capitalism to communism)
And the circumstances by which they've been introduced have some deviation
Communism is something that's done to people (typically against their will)
Socialism is something people often do to themselves (vote your way in, shoot your way out)
In real world practical terms, the end result and lived experience isn't much different for people who are stuck in either system.
The lived experience of someone living in Cuba (who had single-party communist party rule, and saw socialism as the "transitional system on the way to communism" much like the USSR did) didn't differ vastly from someone living in Venezuela, who merely sought to achieve and maintain socialism.
