The provided evidence describes the nature of the apartheid regime (racial segregation, laws, and history), but does not provide data or historical accounts regarding the migration patterns of South Africans to other African countries during that era. There is no evidence to confirm or deny the claim that they 'never flocked' to other African nations.

While the evidence mentions 'anti-immigration marches' in Pretoria and a 'Women's March' in 1956, there is no mention of a specific movement or event called the 'March and March movement'. The search results do not contain this specific terminology.

The evidence mentions that foreign nationals feel unsafe, that there are attacks on foreign-owned shops, and that the national minimum wage has had unintended consequences. However, none of the provided sources explicitly state or provide data confirming that foreigners accept jobs 'far below the market rate'.
