I don't know about Holland and Sweeden, but I know that Norway is RE-DAMN-DICOULOUSLY expensive. I went there two years ago, went to a fast food style burger joint. Granted, I got a GIANT burger, fries and a drink, but the motherfucker was the equivalent of $20.
A beer at my hotel was the equivalent of $10.
I asked a cab driver what a "decent" engineering salary was (I am an enginner, I was there on business) over there and he said the equivalent of around $50,000. If I was over there and made the eq of 50,000 I would be in the poorhouse compared to where I am in the states.
Edit: 3 years is forever. The economic climate will likely be radically different when you actually need to think about this.
