They want to but they can't save everyone, that is the reality because we haven't prepared for this pandemic.
Some country did exceptionally well in the pandemic like China and Singapore
now the government are more focus on the health matters
Some country has already start their economy back otherwise they wont survive this pandemic any much longer. Few months after most country declared their first case of the virus, lot of those country invest heavily into improving their healthcare system but now it would be different. They need to restart everything at the cost of lives otherwise alot more lives will be at stake
