For the great people of Oklahoma, the best of the best also live, work, and perform in OKC. OKC is also the capital (of Oklahoma). I won't touch culture because it's pretty pompous to assign culture to a single location. I'm sure the Sami people disagree with your location of the center of culture,

I'm not comparing cities and I certainly am not implying OKC is the same as Helsinki. Merely pointing out that the OP's comment about Helsinki being a large city with clean air sounded as silly to me as saying OKC is a large city with clean air.

A lot of them live Oklahoma, since it's easy to move to the coasts for opportunities. A lot less people leave Finland (it's harder to do to), so Helsinki gets higher proportion of its country's best.

I'm sure OKC is a great city in many ways, but the best artists in Oklahoma usually move to LA or NYC, engineers and entrepreneurs to Silicon Valley, political leaders to DC, etc.
