Business Unity South Africa (Busa) president Sipho Pityana has called for a “new framework for growth” that addresses, through public-private partnerships, the economic risk being posed by high levels of inequality. Speaking at Busa’s inaugural Business Economic Indaba in Johannesburg on Tuesday, Pityana lamented the fact that millions of citizens remained on the margins of the economy, despite South Africa’s gross domestic product having more than doubled over the past 25 years, from $139-billion in 1994 to $315-billion today.
