You are ignoring the systemic effects: a society were everybody is highly educated is a society were everybody can worked in higher value added areas hence the entire society is actually richer.
Even those who are poor in a highly educated society relatively to others in the same society are still better off compared to people in societies which do not invest in Education - even when that society focuses more on quality of life than wealth production, they live much better because of that society's higher productive capabilities.
The biggest difference between the US and most of Europe when it comes to Education is that the former looks at it as a way for individuals to become more competitive in the job market versus other individuals (a perspective also displayed in your posts) whilst the latter sees Education as a strategic investment to raise the productivity of the entire country, often beyond the mere "money making" and into quality of life domains.
Sweden invests in Education because it allows the country to more and better host higher return Economic areas this pulling the country up, whilst in the US beyond a certain point it has to be individuals investing themselves in their own Education purely for their own personal good.
