"Zucman’s project is that every #billionaire should pay total annual taxes equalling at least #2percent of their #wealth. That, he explained, is the level where they would pay the same tax rate as everyone else. If someone already pays 2 per cent through income and other taxes in their own country, “you are good, there’s nothing more to pay”. If they pay less, then any country where they do business could levy additional taxes to reach 2 per cent. For instance, #Brazil or France could tax Amazon’s founder #JeffBezos, as his company operates there."
