The market timing strategy rationale for investing now is that the world economy and the U.S. economy will resume growing. "I don't need the money for 20 years. Surely by then we will have grown our way out of this." What if that is not true, despite being true for the last 100 years? Western populations are ageing. Populations are shrinking in some countries, like Russia. The real costs of fossil fuel and resource extraction are starting to hit hard. Environmental devastation may unleash more viruses. I'm not predicting, I'm just saying continued growth may not resume or even be desirable.
