Outside Scandinavia, why aren't university tuitions collectively paid for?

Congratulations on living in Sweden. It is a lovely country.

Some other countries do have free tertiary education (Argentina, for example), and in many countries (like Britain) university tuition is heavily subsidised from taxes, even though it is not free. Most of these countries did formerly have free university tuition, but in recent years have begun to charge for it. This is usually because of the neoliberal economic doctrine, with its idea that education is a private investment in one's own future (i.e.,, a means of maximising one's earning potential), rather than the traditional view, which is that an educated populace is of benefit to a whole society.

You didn't mention whether everyone in Scandinavia can go to university if they want to, or whether there is an entrance examination to be passed first. In other words, whether equal opportunity presumes equal ability.

I'll add to my answer once I have that piece of information.

Addition:

Countries are either socialising or economising. This does not correspond to socialism and capitalism as political systems, but refers to societal values of collectivism (the wellbeing of society is more important) vs individualism (personal wellbeing is more important).

Scandinavia must be among the former, while most other (capitalist) countries are the latter.

If eligibility to enter university is based on academic merit, then having to pay IS prejudicial to equal opportunity. Can it be just a question of simple economics that taxpayers are unwilling and governments are unable to afford it? (Perhaps because the majority of taxpayers are not university graduates themselves?) Or is there is a hidden presumption (in some countries at least) that anyone without the tuition fee isn't 'the right kind of person' to deserve to get a degree and a good job?

As an aside, Hong Kong has just decided to introduce 15 years of free education. But in their wisdom, the politicians have decided that it should be 12 years of school and 3 years of kindergarten, not university.

BTW - I went to university on a scholarship, but that's because I was brilliant (and modest!), not because I was poor. Unfortunately, it didn't do me much good because patronage in the job market counts for more than ability and qualifications.

What and bypass over the prospect to extra soak the students? yet I understand that they have got a no longer-Conservative (I daren't call it liberal) Q drop coverage in case the Rapture™ takes position before the 12th day of classes. edit "Y blocks are for little ones" is the line "God is in a Vile mood" makes use of. Hmmmmmm!

I was on a scholarship and paid nothing for tuition

Because an educated population is harder to control.

Because we are broke and we are sending our money abroad as foreign aid instead of making it work for us.
