Economically the Western Cape is self-sustaining, on all fronts. Please consider the following facts: In 2017 the Western Cape contributed R632 Billion to the National GDP and only received  R 50 Billion in return. Since 2010, the Western Cape has only received an average of 8% of its contributions to the total National GDP in return.

We have airports that conform to international standards. We have telecommunications and other infrastructure which is of a first world standard. Once the Cape achieves independence it will yet again become the preferred destination for international investments and the return of expertise to our shores will begin.
