You probably noticed that there's a major social divide in Athens, where people are divided into hierarchical groups: royalty (Theseus and Hippolyta), nobility (Hermia, Lysander, Demetrius, Helena, and Egeus), and commoners (the "Mechanicals" or craftsmen who perform a play at Theseus and Hippolyta's wedding). Obviously, those at the top have a lot more power than the characters at the bottom of the social ladder.
The upper-class characters are also a lot more educated, and the play suggests that this makes them better able to appreciate art and culture, unlike the "rude Mechanicals" who bumble their way through a performance of a classic story. At one point, Egeus says the craftsmen are "hard-handed men that work in Athens here. / Which never laboured in their minds til now" (5.1.76-77).
We also want to point out that the play's division of power isn't limited to Athens—even in the fairy world King Oberon and Queen Titania are elevated above regular old sprites (like Puck) and the fairies who live to serve them. To some extent, all of this is a reflection of the social hierarchy in Shakespeare's England, which also consisted of royals, nobles, and commoners.
