Belgium has cross-cutting differences. It has three linguistic groups:
The Dutch, who were economically backward, the French, who were richer and the German.
This difference in statuses caused distress that was resolved by the government by introducing constitutional reforms that allow the equal representation of all the ethnic groups in the cabinet of Belgium and allows them to address their economic and social issues. This step prevented the occurrence of overlapping differences as it had happened in the case of Sri Lanka.
