Except that none of those things are true.
A McDonald's Quarter Pounder is 86 NOK (8.30 EUR or 9.34 USD) here and 6 USD in the US, 5.40 EUR in Germany. So yes it is more expensive than the US or Germany but still not outrageously so.
The one hour train journey from where I live to the national airport is 298 NOK (29 EUR, 32 USD).
