I fully agree, although it's a great way to quickly lose your billionaire status. Only the greatest of billionaires could afford to build an underground railway system for a city and still have money left to build some apartment buildings for people to live in them. Only a couple of them on the entire earth could pull it off probably. One of them has already done 3 similarly grandiose things and is now dabbling with social media. One of them is in his party on a yacht fase. One of them is starting to get a bit geriatric but also has always cared more about the people on the planet than the planet itself. And one of them seems to be on an internal journey discovering his masculinity. There's a couple more for sure, but I guess they're not in the media enough for me to know what their excuses are.
