> we'll need the people to actually fight the war itself.
Will we? It appears to me that modern war works substantially like modern factories - you don't actually want a large mass of semiskilled workers to pull the levers, each of which can substitute for a different one on about five minutes' notice. You want relatively few, highly-trained specialists to instruct the ~~robots~~ drones. It is perhaps less true in war than in manufacturing, quantity still has that quality all its own, but it seems very unclear that just raw numbers of soldiers will be an important bottleneck as between Great Powers.
I'm pretty sure most of the robots and drones are manufacturered in China though. Even if they weren't, a lot of critical components for building things come from there now.
If there is one house per person then approximately every person gets a house, because almost everyone is willing and able to pay more for their first house than even a very wealthy person will pay for a second one. If there are 1.5 houses per person then you will have to work quite hard at being homeless.
This is wildly incorrect, wealthy people are far more likely to be able to afford and willing to pay more for excess housing than an average person. Especially if they can turn around and rent those houses at a profit.
Houses are an asset. Wealthy people in search of assets will buy the houses and rent them back to you. Or they will invest in companies that buy the houses and rent them, or banks that buy them and mortgage them for a profit.
> Maybe they just have too much electricity up there that is not needed by the population or existing industry?
Yes, this is basically the case. It's quite expensive to transfer power across several degrees of latitude, and as a result, the price of power in the south of Norway is sometimes orders of magnitude higher than in the north.
Because "mostly" does a lot of work in that sentence. Companies, like militaries, keep secret a lot of information that would be safe to release because they don't know which bits are highly unsafe.
