Just seen that Buzzfeed have published an article on why Sweden is so great
These are the reasons they give are:
Parental leave
Free education
Paid education
5 weeks paid vacation
Sick children care
Health care
Child-allowance
Work 40 hours a week
Surrounded by good-looking people
Swedish FIKA
While some are pretty valid (I'm so jealous of free education!), the surrounded by good looking people is a little silly
