South Africa have been experiencing this issue for a long time ago, because of the following causes:

1.poverty
2.unemployment

Because of this causes we tend to forget that our background doesn't necessarily determine our future or failure in life, people can still rise above their circumstances.

Poverty and unemployment can lead to some serious consequences such as:

1.ageing population
2.it will be easier for people to cross borders

We can overcome these problem by not corrupting the country and do things well,
Employ people and supply good quality raw materials as well as goods and services to the poor ones,
Educate people about the results of crime and corruption .
