So some wealthy people will buy bonds with negative yields, others will buy equity at inflated valuations like WeWork.
Strange times.
Pretty good time to have a lot of money (it's always a good time to have a lot of money), to own a business in a developing economy, to start a "tech" company to be acquired in a developed economy, to be in private equity, or to fraud/bluff your way into a lot of money in a developed economy (true productivity-increasing products/technologies are currently few and far between but globalization of technology and outsourcing is still going strong).
Not a great time to be poor, a saver, a licensed professional, or worker of any sort in a developed economy (aside from working at a "tech" company).
