Inaspettato(?)

Expats are the least paid, there is no way for them to make wealth, the purchasing power is so low, there are only handful of opportunities and everything requires you to learn at-least 2 languages. Expats realise this after coming here, plus visa issues don’t make it easier to just pack-up and leave.

So yeah, expected.

The top 10 are one of the following

-poor (I don’t mean that as offensive) compared to USA – where the majority of expats are from. Meaning money goes far

-petrostates. These places need foreign expat expertise to help them be competitive in world market. And for expats to literally come over and prop up their small and coddled citizenry

Luxembourg is neither of these. If would be far more interesting to see stats on where people settle down long term.
