I think the that is being ignored is the emphasis on early learning in Finland. Americans who make a big deal about Finland do so because they think that Finnish students don't start learning until they are 7. The fact is literacy and early learning are hugely important in Finland. If opponents of early learning were aware of that, you wouldn't hear so much about Finland.
"conservative and libertarian opponents of increased early childhood investment have seized on Finland, where compulsory schooling doesn’t begin until age 7, to bolster their arguments. Earlier this year, the Reason Foundation’s Shikha Dalmia and Lisa Snell wrote that, “Early education in general is not so crucial to the long-term intellectual growth of children. Finland offers strong evidence for this view. Its kids consistently outperform their global peers in reading, math and science on international assessments even though they don't begin formal education until they are 7.” But, while Finnish children don’t begin formal schooling until age 7, that doesn’t mean they’re lacking for education before that. In fact, Finnish children have access to very high-quality, affordable child care that meets most of the standards for what we in the United States would call preschool."

Here is an overview of the Finnish preschool curriculum:
"The core curriculum does not divide instruction into subjects or lessons, but it does include various subject fields and objectives. These subject fields are: language and interaction, mathematics, ethics and philosophy, environmental and natural studies, health, physical and motor development and art and culture."

Also, being ignored is that about a third of Finnish children learn to read before starting school.
"When children start school...they already know a lot about reading and writing and some have even learnt to read.
Reading is a valued skill in Finnish cultures. Early readers are seen as talented and people who read a lot are respected."
Learning to Read, Marja-Kristiina Lerkkanen
The anti-learning crowd also likes to point to Finland because they think they don't have exams. But Finnish students have to take a tough series of exams before graduation. We have lawsuits in the United States when easy exit exams are proposed. Students are given no incentive to work hard in school and then we wonder why we do so badly on international assessments.
