I suppose I see the benefits here mainly as a parent. I am so impressed (so far) with my experience of the Belgian system:
FT education on offer from 2.5 - 18 years.
Schools open from 7.30am to 6(or even 6.30)pm
Holiday clubs run by the local education service - between 20 and 40 euros per week.
Lots of alternative holiday activities and cheap clubs/sports facilities
A culture whereby dcs actually do these things rather than hang round the streets.
Firm discipline in class, and strict rules about attendance etc. Parents generally much stricter too.
The lack of "pub" culture ie going out to get pissed and children generally welcomed in cafes and restaurants
University/HE places available to everyone who passes their School certificate at low cost - and none of this A* nonsense.
The option to follow a "technical" vs an "academic" track at Secondary level.
Child benefit that goes UP the more children you have, and is not dependant on income.
A tax system that includes child/dependant spouse allowances with all child care - to include afterschool care and clubs/holidays etc - tax deductible. (household help such as cleaning/ironing is also covered)
Equal amounts of parental leave for both parents which can be taken all at once/in chunks until the dc is 12 yo.
With all of the above - I honestly see that it is much more beneficial to my dd to stay here.
