Economic development is a major issue in South Africa, with the country experiencing high levels of poverty, which are connected to the enforcement of socio-economic rights. There have always been calls for Africa to unite for it to prosper. Intra-African trade is a call for Africa to trade more with itself towards its prosperity. It is further said that intra-African trade will enhance sustainable development and economic growth, and it is important. The purpose of the paper is to establish that there is a link between economic development and the enforcement of socio-economic rights. Further, this article argues that there is an urgent need for economic development in South Africa to improve the enforcement of socio-economic rights. Through a qualitative desktop-based methodology, this paper argues that trade is the main factor of economic development. Further, South Africa must focus on intra-African trade. By dealing with this economic gap, South Africa will accelerate sustainable economic development and consequently the enforcement of socio-economic rights, which will in turn reduce poverty and better the lives of millions of South Africans who are in dire need of socio-economic rights to be enforced due to the living conditions they are in. The South African Constitution is examined, and it is noted that it fully protects socio-economic rights as it has socio-economic rights in its Bill of Rights. However, it is acknowledged that there are other factors that affect the enforcement of socio-economic rights, such as corruption and the separation of powers, which are identified.
