How many Soviet republics were there?

No sane person would refuse the right to make economic decisions and give up their family (if they have one) and voluntarily offer their wife for public use.

Gur, you seem to be confused. There is no concept of exchanging wives in communist theory. "Free marriage" was advocated by nihilists in the 19th century, but nihilists evolved into anarchists, not communists... In the USSR, on the contrary, the thesis "family is the cell of society" was promoted, to the point that people were publicly reprimanded for marital infidelity (this, of course, sounds ridiculous, but if compared to the swingers lifestyle promoted today, it is perhaps even preferable). I won't talk about divorce rates; everyone already knows that. People have somehow forgotten how to create families these days. Well, the topic of benefits for families has already been discussed, and that's not what I'm talking about.
Before anyone jumps on me, I want to clarify that in this post, I am not advocating for the USSR, but simply clarifying facts. I just wanted to correct you: you seem to have gotten something wrong about the family. This did not exist in either communist theory or socialist practice.
