Virtue signaling is the expression of a conspicuous, self-righteous moral viewpoint with the intent of communicating good character. (Wikipedia) Hypocrisy is another good word that describes Jeff Bezos. (and so many of his fellow billionaires) Why? Read this.
Apparently, new owners of luxury yachts are supposedly considering their environmental impacts. “Solar panels, wind turbines and hybrid-propulsion systems are increasingly common on luxury yachts. Jeff Bezos, the boss of Amazon, may be setting a new trend. He took delivery in April of ‘Koru’, the world’s largest sailing yacht at 127 metres. There is a drawback to relying on wind power. ‘Koru’ is followed everywhere by a diesel-engined support vessel carrying extra supplies and even a helicopter pad. At 75 metres it almost qualifies as a mega-yacht too.” (The Economist)
Can you think of some other words to describe this? Lunacy comes to mind.
