Because, unlike today, there used to be LARGE DIFFERENCES in how different communities spoke with each other. Money, ancestry, intelligence, location, race, education, they all influenced speech and that was both noticeable and judged. To be "well-spoken" was highly regarded and indicative of high-class. To be shallow and blunt was an obvious marker of trash. This is (was) true of ALL cultures THROUGHOUT history on planet Earth.

Most of the people focused on in the Ivalice-setting Final Fantasy games are extremely high-class. Royalty. The exceptions to that trope are obvious just in how they speak.
