Roaring 2020s? Here's The Post Pandemic Best-Case Scenario Could the 2020s be an era of prosperity? The pandemic has paved the way for digital, biological, and ecological revolutions. PARIS — Within 18 or maybe 20 deadly months, we will all finally be vaccinated. We will want to live like never before. The holidays will be beautiful, the skies will be clear, and artists will be celebrated once more, just like a century ago, in the 1920s, the years nicknamed "crazy" in France, "roaring" in England, and "golden" in Germany. It may be easier to imagine bleak scenarios. Perhaps by mutating, the coronavirus will escape the vaccines that have already been developed. Perhaps our fragile society will be torn apart, or even collapse. Maybe, by rejecting "business as usual" many companies will go bankrupt and others will be unable to invest in the future. Even worse, maybe banks and governments will run out of money, triggering a severe financial crisis.
