"Imagine the agony of two million more people," said Luke Johnson, a prominent UK businessman, "How many deaths might flow from that?"
US President Donald Trump made similar claims in late March, telling Fox News: "You're going to lose more people by putting a country into a massive recession or depression."
His Brazilian counterpart Jair Bolsonaro insists that economic stagnation will hurt Brazil more than the virus itself, and on Thursday called the decision made by governors and mayors to close some non-essential sectors of the economy "a terrible disgrace."
These arguments are unconvincing, say economists. To fix the global economy, fix the global pandemic, they add. Survey data shows the US economy was winding down even before US states were mandating stay-at-home policies. Fear of the virus mean people were shopping less, small businesses were closing and cutting employment.
"None of us [economists] have enough information to know if lockdowns are worth it or not. We are not operating in the realm of perfect information or even much information," Thomas Hale, associate professor in public policy at the Blavatnik School of Government at Oxford University, told CNN.
Studies of previous recessions have shown that all-cause mortality tends to fall during them, although suicides increase. During the Great Depression of the 1930s, it was found there were declines in mortality and gains in life expectancy, according to a research paper in Proceedings of the National Academy of Sciences of the United States of America.
But there is no precedent to the scale of the lockdowns enacted around the world to combat the coronavirus. The best we can do, say economists, is to track the emerging evidence.
"We don't know much about the epidemiology of this disease; we don't know how long it will last, how the economy will react -- these are all big unknowns -- so the best we can do at this point is follow the evidence we do have, be completely committed to following the science and updating our strategies as we get new information," Hale added.
There is no doubt that lockdowns have wrought economic chaos. Restrictions launched to counteract the disease have exacerbated existing inequalities in education and the workplace, and between genders, races, and socio-economic backgrounds.
Academics warn of a new lost generation as more disadvantaged students face increased obstacles to achieving good grades under lockdown. Historically underpaid, women are the hardest hit by the economic slump in the US, according to figures from the Bureau of Labor Statistics.
In Britain, men working in low-skilled jobs are dying from coronavirus at a higher rate than their white-collar peers. Migrant workers, treated as second-class citizens in the Gulf, Singapore, and India, have found themselves unable to afford their next meal or suffering the brunt of the coronavirus outbreak in those countries.
Yet there is widespread agreement among world-leading economists, such as the Chicago Booth School IGM Panel, that lifting severe lockdowns too soon could risk reigniting second waves of the virus that would inflict still more financial pain on societies.
The point of shutting economies was to save lives. It also helped governments buy time to scale up their testing, tracing and isolating regimes, which have helped countries like Germany and South Korea isolate and tackle future clusters or outbreaks until a vaccine is developed.
But Hale says some countries, like the US, have squandered the time given to them. "Other governments haven't used that time well, and I would say the United States is very much one that, at the federal level, has not had a coherent strategy."
A failure to use the time wisely risks a spike in infections as lockdowns are lifted, and a subsequent nosedive in consumer confidence.
Robertson points to Sweden, which adopted a different strategy to other European nations during the pandemic -- keeping most schools, restaurants, salons and bars open. It did, however, ask people to refrain from making long journeys, placing an emphasis on personal responsibility.
Despite its different path, Sweden's economy is in the doldrums along the rest of its European counterparts, and it has more deaths per capita, over a seven-day rolling average, than its Nordic neighbors, according to Our World in Data, an independent statistics website headquartered at Oxford University.
Rich, developed nations may well be able to afford extended shutterings, says Robertson. But low-income countries in South Asia, as well as Africa, cannot afford to rack up high debt, lose tax revenues and investments to its economy, he added.
The question, he said, is more pressing in countries where millions "badly need to have an economy that is working and growing."/cnn.com
