“A billionaire's idea of vacation is in space, whereas a regular person's idea of a vacation is on some island or in another continent. And if the billionaires are abusing resources for personal enjoyment, so are these regular people. You have no right to demand moral accountability from billionaires, if you yourself don't mind engaging in your everyday luxuries – for your luxuries may seem dim compared to those of the super-rich, but still the resources you spend on them could feed and clothe at least ten families in developing parts of the world for a year.”
