Some experts think otherwise:
"When the global economy recovery arrives, it may look more like a “swoosh” than a V, according to Davy, Ireland’s largest securities firm.
“It’s like a Nike-shaped swoosh,” Aidan Donnelly, head of equities at Davy’s private clients unit, said in an interview. The firm has assets worth over 14 billion euros ($15.4 billion) under management."

"The virus won’t last forever, the global economy will recover,” said Donough Kilmurray, Chief Investment Officer at the Dublin-based firm’s wealth management business. “A V-shaped recovery feels too optimistic, but an L-shaped view is probably too pessimistic.”
We were overdue for a slump even without the virus such that we probably should assume it will progress (or not progress) like a typical modern slump, with its slow recovery.
Ideally we'd pay down the debt during the up times so that we can have big stimuluses during slumps. There's a lot of old infrastructure to be repaired in the US anyhow. Unfortunately Wash. DC lacks such discipline: they failed to save up for a rainy day, and it's pouring now.
