Yeah, I like it.
The Muslims will live on surface while the native-born Dutch will live underground.
“AMSTERDAM is to go underground as overcrowding”
“which will reduce the pressures of overcrowding”
“There has always been a lack of space in the city”
“are also feeling the strain of overcrowding”
Solution: Deport your large Muslem population. This will solve the overcrowding, decrease strains on your social services, decrease crime, and improve social cohesion and national unity.
