I'm not sure that birth in Belgium is necessarily the point. In the UK for example we have for various reasons done away with the concept of 'patriality' where merely by being born in UK (or indeed on UK registered ship) one becomes British or indeed have a right to live here.
e.g. There used to be an even greater problem problem with the daily Lagos-Heathrow-Hillingdon Hospital flight when the punters were giving birth to 'British' children who had a right of abode in UK!
See here the problem in Ireland

This certainly flags up the fact that with the liberal/lefty concept of multi-culturalism where all cultures are considered equal and diversity from cultural norms of our society are to be 'celebrated' rather than 'worried about' we are partially responsible for the state we find ourselves in.
As we used to say the fact that Jesus was born in a stable does not make him a horse.
