How can you blame the world leaders for destroying their country’s economy and the world economy.
How could have they known that simply confining the age 55+ or with prior medical conditions and setting up processes to protect them (such as having all workers working in old age facility needing to wear hazmat suits...), while keeping economy open would have flattened the curve.
Other policies could have been. Nobody age 55+ or with prior medical condition could travel into (or out of course) the country
Instead of shutting resources, the government could have supported hazmat suits companies for them to scale up production (Elon could have put such a production plant up in no time).
Instead of moving forward. The answer was to stop and hide. The soy consumption around the world is just too high. Look at the Canadian Prime Minister for example. Xe hid in xyr house for 4 months.
Hindsight is 20/20 of course
