And all the other stuff the US had first, that was just coincidence was it?
Yes. Same goes for the things that USSR had first.
Really though what the left like to call the traditional or nuclear family is nothing of the sort. It's an artifical creation put in place to give returning soldiers a place to go.
You forget the soldiers that return dead. This is the missing workforce women were set to replace.
You know your Rosie the Riveter quit her job after two weeks, right?
Who cares about one specific woman? It is only an anecdote, not data.
Read up on the events immediately following the 1917 revolution. They don't agree with your narrative.
Maybe you have read the wrong books then? In the USSR women worked literally everywhere, there were no jobs considered "too manly". In modern capitalist Russia the position of females became, in fact, way worse. But if you really want to know about things that happened immediately following 1917 revolution: USSR was the first country to legalise abortions. USSR had equal rights and women's suffrage starting with the first constitution of soviet Russia - in 1918. Compare that to the 19th amendment which is from 1920.
The thing is, second world war has slashed the soviet male population by a huge amount, thus after the war has ended there were far more women in the workforce than men. Actually, if I remember correctly then women were the majority (51-52%) of the soviet workforce for decades.
