prosperous and under
Communist control
The West

 To see a united,
democratic Germany
The East

Increased tension between neighboring countries or among
citizens within a “walled” country (e.g., East Berlin)
Increased isolation (reduction in the diffusion of culture)
Stigmatizing of excluded population (either internally or
externally)
Promotes nationalism, reduces foreign influences, increases
xenophobia
Illegal crossing of the border becomes more dangerous
Separation of families, friends, relatives, cultural groups
Increased protection/security from either real or perceived
threat
Reduced face-to-face interaction between people of
neighboring countries
Increased virtual communication between people of
neighboring countries
Reduced migration
Cost of construction, maintenance, staffing

staffing
• Reduction in flow of illegal goods

• Loss of job opportunities for those excluded, less
money earned/sent home, reverse remittances
• Loss of cheap labor
• Increased cost of smuggling (humans, drugs,
other goods)
• Reduced seasonal migration
