Poverty in Norway is not so much about starving or not managing to pay utilities bills. People can overlive (survive), but not really live. This is mostly immigrants from non-Western countries, but also other people who are on benefits, unemployed or underemployed.
Kids not being able to "fit in" with the rest of the kids because their parents can't afford all the little extra costs. Birthday parties, school trips, prom suits, bikes, soccer club fees, electronic gadgets, snowboards/skis. If you don't have all the required middle class accessories or more, you'll struggle finding friends other than among other poor kids. The house/apartment is so shabby that the kid is reluctant about inviting other kids over, maybe he or she doesn't even have his own room.
Personally, I've had a quite privileged middle class upbringing. My parents have big mortgages but can still afford to drink good wine and travel to exotic places once in a while, and we've never really been in any big need.
If I decide to not get a job while studying at uni and try to survive off the meagre student loan, which is tempting, I will probably have to live in near-poverty.
