When I lived there, home-made spirits aka moonshine was popular - people used to lace the low alcohol beer with it, first and last time I have ever tried home made spirits. I know - it's very dangerous.
The Hembränt (moonshine) still exists but is much less prevalent than in the 1990s/2000s unless you are in the sparsely populated North. These days there are (not actually legal) organised groups that buy and bring in booze from the EU and sell it on. In the big city (DD informs me) there are telephone numbers that student parties can ring and 15 minutes later a case of beer or bottle of vodka will be delivered (one of the downsides of not being able to buy at Systembolaget, the state off licence until age 20),
I can't find it now but I read a article about the alternative reasons for cheap childcare was that the state did not trust the people to parent, the state believed it could bring up children better than most parents and providing very cheap childcare was designed to encourage parents to willingly give up their kids to the state for parenting.
I have this - but it certainly sounds like the stuff the far right and Christian Democrats were writing about 15-20 years ago when they wanted to force women from the workforce onto low paid SAHP benefits. Childcare started in the 1800s for working single mothers. The expanded childcare provision goes back to the post-war industrial expansion. Sweden was not badly damaged so industry expanded rapidly in the 1940s-50s - so basically women were needed in the workforce and it needed to be an attractive option - but sure there were some writers on the left who saw it as a social experiment (Alva Myrdal?).
These days there are a lot of options - you don't have to use local authority nurseries. Just in my little, very rural area there are many options LA, Montessori, Steiner Waldorf, Christian, Forest School etc. I was a SAHM for 3½ years but TBH you forgo a lot of working benefits - in particular you never want to lose your earnings related sick/unemployment pay in Sweden as they control sick pay, unemployment benefits, maternity benefits, pensions and other working benefits - (it used to annoy me when I went to aquarobics that I was one of very few that actually paid - most of the others got an hour of paid activity from their employers). You also pay a higher tax rate if you don't work
There was a policy for SAHP in the mid-2000s introduced by the Reinfeldt Government at the urging of far-right and Christian Democrat coalition partners. Parents could be paid to stay at home until their children turned 3 - you got 3,000sek a month (about £240 then and approx $425 today). It was mostly adopted by Conservative councils - but it was controversial and regarded as a trap for women and especially immigrant women who lost access to many earnings related benefits and especially given that parents had many rights and benefits that paid a lot more. In the end only 115 councils (of 390) introduced it, take up was very low, and the policy was abandoned in 2016.
