There's a big difference between a "near-collapse" and a "collapse" - a big difference between losing your life savings due to a bank failure and not losing your life savings due to a bank failure.The 2008-2009 recession was triggered by a near-collapse of the financial sector, and these types of event have historically led to longer economic downturns (the best example of this was the Great Depression of the 1920s).
The 2008-9 recession was just a bad recession and bad recessions take longer to recover from than less bad recessions simply because they are worse; more ground lost means more ground to make-up.
I'm generally an optimistic guy, but I'm not optimistic right now. I think the way that the pandemic is being managed is a dismal failure, the plans for how to manage it for the next year can't possibly succeed, and so until we see a vaccine or the pandemic naturally burns itself out, we're going to see a lot more death and a protracted quasi-shut-down state or cycles of openings and closings.
Hopes for a "V-shaped" recovery are based on the idea that with immense stimulus you can keep people economically health so when the economy re-opens in a month, everything goes almost back to normal. I don't think either premises is likely. There's a lot of real damage being done that will take time to undo, and I don't think we'll be able to go back to normal anyway due to the continuing pandemic. Add to that trillions of dollars of new debt on an already high debt load, and we may see a long recession and a new normal that is decades of stagnation due to a need to pay-back all of our debt (including the medicare and social security shortfalls that already threaten the 2030s+).
