I don't disbelieve Whippet's experiences at all, I think Sweden can be immensely difficult to move to as a foreigner, and as a poor student stuck in Stockholm in the 90s... brrrr. I don't recognise the passport thing at all though. Wondering if someone misinformed you and that would just have been the final turd in the fan for you I suppose!).
I think you'd have had a much more positive experience as a student in Uppsala or Lund, as you say, and likely your recollections would be more of the "they're odd people but I got on with a good few alright and went to some great parties". ;) I think it can be very tough for Irish people, the culture is very different and could certainly exacerbate feelings of loneliness. A writer, forget who, wrote about a foreigner coming to Uppsala on Walpurgis (last of April) and being blown away by the atmosphere! the party! the joy and friendliness of the people! and deciding to stay. Come November they didn't know what had hit them, lmao.
It's ridiculous to assume Sweden is some sort of equalitarian paradise of course. I direct you all to the recent UN criticism as regards women's rights www.ungeneva.org/en/news-media/meeting-summary/2021/10/la-suede-joue-un-role-de-chef-de-file-en-matiere-degalite-entre
I'd also like to say that the discussion on how young children in preschool should be and for how long is ongoing here in Sweden. And I think it's naive to refuse to admit that some children are in preschool because it's convenient to parents who get "me" time. Preschools are not all little cozy family-run units, they can be very large and feel quite impersonal (parents in bigger cities/towns might therefore shop around a lot before deciding). (But for the record, they're supposed to be a resource for parents who need childcare while they are working. Ie you're not even supposed to swing by the shop on your way home before picking up the kids, you're supposed to pick them up first and shop after.)
There's definitely a lot to discuss about how much we actually permit individual needs to influence childcare and personal life. The Swedish system is sort of rigged so that whether it's the best choice for your individual child or not at that particular time, you will be putting them in childcare at 18-24 months of age. The UK system is rigged so that children are put in uniforms at the age of four and sent to school, , whether the child is really emotionally able for that sort of structure or not, with little opportunity for unstructured play during those hours and very little outdoor space. I mean we all operate within the constraints of society, none of us are truly free.
And this is why the Swedish system is organised so that almost exclusively women can't as easily "freely choose because it just happens to be the best thing for our family" to be home with children for about ten years of their working years. It's set up so that in theory women can work full time. In practice women have still been doing most of the unpaid household labour and we have had a culture of almost exclusively women "freely choosing because it just happens to be the best thing for our family and after all he earns more money" to work 75%. Change happens slowly and other incentives are probably needed. Privately outsourcing domestic labour to other women (nannies, cleaners) doesn't solve THAT problem.
