Maybe I misunderstand you then, to me you made it sound that was a given. Those companies have undoubtly different history and, to me, rent is a relatively recent issue and over hundreds of years it might not be a factor. I pretty sure national mints have been moving around for instance. They are not location dependant.

That said, I might be wrong, it would made an interesting study to try to acertain what are the common factor to those companies. If any.
