Mayhap, Silva, you are expecting every Miqo'te to behave the same.
Yet you will notice a great difference between those of Ul'dah, wherein one has to do whatever it takes to garner money, those of Limsa, wherein respect is gained from the blood in your axe, and those of Gridania, wherein piety and reverence are the law.

Miqo'te fit the 'catgirl' theme according to how it would be in each different city-state, you will find the dancers to basically be ul'dahn (with the exception of the ones in Costa, but, Costa).

(note the moonkeepers are mostly from gridania)

Also of note is that there is at least one very amazing romance between a miqo'te and an elezen, which is in the ALC questline.
