It's not strongly related to any of those things. The situation would be very bad in Norway/Denmark too if we didn't react like we did.

Compared to both Sweden and Britain, Norway reacted quicker and harder, with way more testing than most other countries. As it got out of hand, even more restrictions like shutting down a lot of business types, public transportation, schools and travel was added. Working from home was also recommended and used by basically everyone who could. Long after this happened in Norway, things where mostly as usual in both Sweden and Britain, despite the number of infections climbing fast.
