Just to clarify, it’s not totally free in Sweden, and the whole approach is very different from how I understand it to be in the UK. Universal public nursery/preschool care is very heavily subsidised by the state, with parental contributions capped at a maximum of ~£150 a month for highest rate tax payers. Provision is regulated by the state who fund the majority through grants and general taxation. It is near-as-dammit universally popular, across the political spectrum.
Whereas the UK seems to abhor anything that looks vaguely like state intervention, hence you usually choose either to be shafted by employer or government (or both), and pay a shitload more for the privilege of childcare that is effectively unregulated (in terms of the extent of provision/ access, quality, and “the market”).
PS- any arguments about the impossibility of state funding or regulation in the UK could usefully be prefaced by a comparison between the respective SE/UK budgets for, let’s say, childcare and “defence”. I’d be interested if anyone had a nice pie chart showing that, maybe done as a % of trident replacement schemes 😉
