That didn't work well at all, sadly, besides the initial boost. By the 80s abortion was common, but it was done illegally, often leading to deaths or severe illness. Unwanted children in a collapsing economy was disastrous, and were abandoned to be taken care of by the state, which was also collapsing and was unable to provide.
These half-bakes solutions are often insufficient. Like in Hungary today, where the intentions and even welfare state are provided, but feminism and liberalism have corroded society to such a degree that it's really, really hard to stop the train. Even with Orban. Even with the 98% Hungarian cohesive state.
Still, partial intentions are still better than nothing.
Another important factor is geopolitics.
For example, because of the competition and the brainwashing fallout of the WW2, USSR and the West often took reactionary positions to what the other did. It's seen even today with Russia and Ukraine, two countries with very, very similar cultures, but reflexively pushing against what the others do. Is the West now progressive? Trad Russia. Is Russia now trad? Fuck that Ukraine is gonna legalize fag marriage, that will show the vatniks! It's just endless and it's so incredibly retarded.
Even in Romania, nowadays socially RW positions are suddenly associated with Russia to the point where you get suspected of being pro-Kremlin if you're anti-progressive.
The US is also doing this. The more Russia and China push towards more totalitarian states, the more Washington moans about democracy and liberalism, minority rights and so on, even though they couldn't care less is Israel is genociding a whole island of dindus.
I think that social conservatism, which I really hate as a term but sounds better than socially right wing, should consider at least 3 categories:
- women rights and what was done, when. Suffragette movement seems to be a pretty Western phenomenon, but the truth is the USSR was also highly progressive, at least in policy, as attitudes did not change much, just like in the West
(important modern extension being gender politics, i.e. the smolbeanuWu queer and trans crap)
- minority rights and ethnocentrism/how normalized it is; as an extension there are racial politics, but that's more of an American thing
- individual rights and freedoms
Separate aspect which is so large that it kinda requires its own topic is the economic aspect, and the tendencies of capital and markets, which I don't think they are neutral, as they always lean towards cheap labor and mass production, which works best inside libertarian, less regulated societies.
Also, a government that is able to punish corporations when they go nuts on some undesirable direction, like social media, is highly useful when it comes to implementing some basic social norms. Nationalizing rebellious capital is always tempting, but comes with its own set of dangers. Nationalization, if you have the proper government and laws in place can fix a lot of defective stuff. For example, a nationalized Twitter would be forced to abide by the 1A as it's run by the government. Imagine the chaos.
