The informal economy covers huge stretches of Egyptian society and raising money through group events (rather than banks) comes from the traditional collective savings arrangement that Egyptians have used for years. The most common form, is when family and friends hold money collectives. Others are fake weddings where those who attend bring cash for the host.
Raising money through group events comes from a traditional collective savings arrangement that Egyptians – and others across the developing world – have used for years. The weddings are sometimes real and those who attend bring cash to help launch the young couple on their new life. At other times, wedding-like parties without an actual ceremony pop up as a means of mutual funding. The most common form, however, is when family and friends hold money collectives without celebrations. All three kinds continue to thrive.
