You pick the most dramatic predictions given on the premise of NO ACTION taken, made by SOME experts. Reality is that no expert in any Nordic country made any such predictions. That was something some experts in the UK started talking about. Nordic health authorties and especially Swedish ones predicted far lower number of deaths and consequences.
Contrary to what you seem to suggest here, the results in Sweden has been far worse than their own predictions.
And keep in mind the predictions you refer to related to doing NOTHING. Sweden isn't doing nothing. It is in fact doing quite a lot. Swedish citizens have followed government guidelines and use of public transport, restaurant visits, shopping etc is way down. People are practicing social distancing in Sweden, which surely has contributed to keeping their numbers down.
Still their numbers have repeatedly been much worse than what their predictions have been. I have followed Swedish health authorties in the media. And again and again they have been wrong.
You are cherry picking one view, and removing all the caveats given to present a completly false representation of what predictions have been. You are trying to push the narrative that health experts are alarmists who have deceived us all, want to control our lives or whatever.
