Jeff Bezos made his fortune on the backs of underpaid and unprotected workers.
Furthermore, Amazon paid $0 in federal income taxes on more than $11 billion in profits before taxes for 2018.
Asked to donate big chunks of their fortune to tackle the COVID-19 pandemic, the super-rich have been responding in different ways.
Mark Zuckerberg has committed $30m to the Bill and Melinda Gates Foundation. Not enough, critics say. Zuckerberg has an estimated fortune of $67 billion.
Madonna has donated $1m to the Bill and Melinda Gates Foundation, to help in the creation of a vaccine.
Jeff Bezos has donated $100m (£80m) to the food bank charity, Feeding America. Not enough, critics say while pointing out that the donation represents less than 0.1% of his estimated $123 billion fortune.
