Many times in the Star Wars movies we hear reference to "Corellian" space ships.
An example, Han Solo says in the cantina: Not the local bulk cruisers mind you, I'm talking about the big Corellian ships now.
Now in Solo: A Star Wars Story, we see the planet Corellia.
There is a lot of ship building, but otherwise the planet seems pretty terrible. In the movie, it is said "no-one wants to go back to Corellia".
Han's own father worked on the "CEC" construction line to make ships like the Millennium Falcon.
So, why are "Corellian" ships so good, given that they are they mentioned, almost revered, at so many points in the movies?
Sure, I can imagine some of the best star ships were made on Corellia, but aren't there other ship building planets in the galaxy?
It seems unlikely that all the best ships (both alliance, like Princess Leia's ship, and Empire, like Star Destroyers) are made in the one place.
Is there some local advantage (for example, plentiful resources of a certain type, or low gravity, or proximity to mining colonies, or whatever) that make ship building there ideal?
