@urlyman pointed me to this podcast with Fadhel Kaboub that starts with:
“If you divide the world into rich and poor countries – global north and global south – and you net out *all* the global financial transactions – meaning you include exports, imports, interest payments, debt payments, charity, foreign direct investment, including illicit transactions – you find that the global north takes $2 trillion a year from the global south.”
$2 tn a year.
