Wow, one of the few times I get to be proud of lil ol' Belgium.
I often joke with family that we live in the best country in the world by default. Not because it's a paradise by any stretch of the imagination but because the rest of the world went to shit faster than we did.
Hmm, surprised it's that much lower - wonder why?
Maybe 1% in .be hide wealth in .lu , and fgov is not good at tracing it.
Also chateaux in the south of belgium seem relatively cheap (wrt elsewhere).
