What is the actual point of the G20?

In a podcast discussion, South African hosts highlight the stark contrasts of natural beauty and decay in rural areas observed during a recent trip, while critiquing persistent economic challenges and previewing the upcoming G20 summit amid a U.S. boycott announced by Donald Trump. They debate urbanization trends, populist policies like New York Mayor Eric Adams' state-run supermarkets, the persistence of bad ideas, and the fairness of credit rating agencies in downgrading South Africa despite unmet debt projections. The conversation underscores the urgent need for public-private partnerships, measurable reforms, and action over promises to restore investor confidence and achieve sustainable growth.
