Norway? Massive oil reserves and natural resources in a country with a small population. Imagine Quatar with a more sane government and much more sane (and richer) neighbours. Plus self-sufficiency in terms of agriculture.

Switzerland? It was the one neutral country where everyone parked their emergency money. They played all sides in ww2 and won. Everyone needs a neutral ground to negotiate and put their fuck-off money.

Both very exceptional cases.
