Places that
people want to live. Which are often aspirational. Plenty of people live in places that would be 2nd, 5th, or even 10th on their list if money were not a concern, eh? And that’s normal. And almost everyone
could live in those out of the way places too.
Which is why comparing against the rest of the country is valid. Just like comparing SF to Vacaville. Or South SF. Or Oakland.
There are definitely parts of Paris that your typical Parisian (or even atypical French citizen!) cannot afford to live, yes? And many, many live in Paris’s equivalent to Oakland. (Or NYC’s Harlem)
It could be better - but people also have this weird mental block where the only place they ‘can live’ is also the same place everyone else wants too, but they can’t afford it, and somehow it is everyone else’s problem to fix that for them.
