Even after the first big wave will be over. This ugly virus is about to stay and it will take many more lives, of people we love and care for. Not just parents or grand parents face a high risk, but people who are or will be in severe health condition due to whatever. Many months are to come and who knows how somebody reacts who is already having a cold or something similar and gets Corona "on top" of it.
What they do isn't just irresponsible, but simply cold hearted. Because the whole world desperately needs a cure and it will take time to produce and ship everything.
