Earlier quoted context omitted.
I'm an American living in Norway, and I can confirm half of what you write: the costs you describe are pretty accurate. However, you drop the ball when you write "It's not affordable unless you're absurdly wealthy." The fact is, the salary range in Norway is high, and quite compressed. Everyone can afford to make lasagna.
Are you KIDDING me? How is this possible? Can you please tell me exactly how much ingredients cost, and what a typical starting salary is for a college graduate in Norway? Not to say "I don't believe you", but I'm incredulous. This is shocking. P.S. Why are you an American living in Norway? How is it?
In terms of salary: I've never heard of a college graduate making less than 250.000NOK = $43,000 USD, even in the most trivial, entry-level job. Note that that's for 32.5 hours/week, with 5 weeks paid vacation and full health care included.
I don't have the lasagna ingredient prices available at home (most items don't have price tags, but shelf-tags at the store), but I can tell you that gasoline is over $7/gallon, if that's something to go by.
