Norway only discovered oil worth extracting December 23 1969. So you would not have grown up in a particularly rich country, but you would see the country gain incredible wealth as you grew older.

If you were born in the early 60s and bought a house in the early 80s, you'd be pretty fucked when the global economy crashed. But I guess that goes for everywhere. The 70s would probably be a better bet in that sense.

You'd probably not live in a city, but in some village in the middle of nowhere. So the wealth of the country would mostly be noticable through the social security web built around you, and the fact that your random village suddenly got a tunnel to it. If you're a farmer you'd receive subsidies so it would be somewhat possible to keep going, even as your peers in continental Europe would run out of business one by one.

You'd probably secretly wish you would also go out of business so you could retire to something less taxing.

You would spend your childhood amazed by America, and jealous of the youth revolution going on there. You'd watch American movies and grow up idolizing American and British war heroes. You would think your stupid valley was the most boring place on earth.

In your old age, you would thank your lucky star you're not in America. Maybe you'd get a house in Spain for the cold winters. Your family would think less of you for it, but they wouldn't be vocal about it.
