I don't think it's surprising, but good research to have backing this up nonetheless. Pretty much every problem in this country can be traced back to the lack of affordable and stable housing. It makes complete sense to me that a state house with security of tenure comes out better than a private rental you know you have for a year at most (and likely less if no cause evictions come back).
Incidentally, the authors of this study have done a lot of research into housing quality too. They found that providing insulation grants for our notoriously cold and damp houses generated savings many times the cost due to less pressure on the health system and fewer sick days from school and work.
If the zoning wasn't regulated to benefit existing owners then apartments would be built, plus new townhouses, and these damp decaying places would be $100 a week. If there was an actual housing/rental market (you know, one with real competition, instead of a market that's propped up by government policy) that could work, but I'm not against insulation requirements. If they sent jackboot thugs to inspect homes and threatened to shut them down if landlords didn't comply, I'd fully support it.
State housing is like winning lotto you get a house for dirt cheap. Of course you are going to be happier than the sucker paying $700 a week for the same thing.
Also, state housing normally means they have the house to themselves. I'm not in a state house or owning, I'm stuck in a crowded boarding house with 10 other people. The group that I'm in always has the lowest satisfaction, I'll bet. Everyone is complaining about each other constantly, that's also how we make friends, by bitching constantly about "the indians" who never stop talking loudly, and complaining about the Chinese landlord ripping us off. I'd rather have a stable house that I don't share with others, like an apartment. NZ lives in the past. Can't believe we don't have apartments in the suburbs of christchurch yet..........
You're not wrong, but having housing is also fun. Easier to take a day off work to go guillotine billionaires when you're not giving all your money to those same billionaires.
I seriously think that if we want any hope of getting out of the mess we currently are in we need stronger local communities - co-housing could be a very real way to enable that.
