It's been around forever and exists everywhere,
but it is primarily a scandinavian phenomena
danish writer aksel sandemose put it down in 1933
basically it refers to:
death to individuality,
you aren't better than anyone no matter what,
being special is bad,
being average is good.
a newspaper editor in my hometown bragged about his old car in his daily editorial,
anything else would have been unacceptable,
talking about his new beamer might've jeopardized his credibility.
this is the law of jante
this law often force scandinavians to move abroad,
I left years ago and never look back.
and I do not see it getting any better.
death to sameness,
long live individuality and tolerance of differences!
