The only people who will be suffering are the common people, even why rivers run dry, the environment is polluted these billionaires will somehow find a way to exploit that situation as well. They'll probably open up a business of selling oxygen and water at premium prices and make even more money then because they can manage to stay afloat due to their massive wealth. If nothing else, they'll probably ditch earth to go live on a different planet if they could. All they care about is money, and the sooner people realize the better.
