The goal of semantics, and words in general, are to convey ideas. It was true in the past that socialism was a very concrete, straightforward thing. If you believed in worker control of the means of production, you were a socialist. Now there are people who say they’re socialist, and they advocate for private tyrannies for the foreseeable future (decades or sometimes even a century+). They want entire generations of humans to be wage slaves, serve the interests of capital, pay their reduced wages to land leeches and banks, and then die without having ever seen a better system.
Those systems, systems by which entire generations of people are subjugated to the interests of capital under authoritarian rule, are now called socialist or sometimes communist. And I no longer have the word to describe a system where wage slavery is immediately abolished (much like chattel slavery was), and workers take immediate control over the means of production.
Those societies/institutions were often overthrown and overrun by either conservative Marxists (e.g Lenin) or fascists (e.g Catalonia).
