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
yes, because they are first world country in Asia, they have good facilities and good government, but other countries are not facing the pandemic effectively.
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
Economy is very important, same us lives of course but it's not always possible to protect both, there are some who would suffer along the way as that's how dangerous this virus is, but it should not stop us or the economy. If in big countries like in the US and UE can't control it, let us expect even worst in small countries if people will not cooperate with the government.
