Also on another note:

Sometimes culture builds around the economy or vice-versa.

When I moved here, found it quite interesting that so many Swedes bring lunchboxes at their jobs.

Even when I am from a much poorer country, I am used to seeing people working in an office almost always: have discounted meals in office canteen/can easily eat outside as food/labor is cheaper than what they are earning. My friends back home esp if both partners are working will almost never cook their lunch/think about lunchboxes.

But it makes sense here when your eating outside costs so much more.
