My Little Pony: Friendship is Magic

[NameGoesHere1066]

I got to give this show a shot. It looks cute.

Question, is their some hierarchy when it comes to the type of pony one is? Like are unicorn and pegasus ponies seen as better than earth ponies? And are the hybrid unicorn/pegasus ponies like the best? Because I noticed that royality or the powerful ponies are the hybred ones. Even though it doesn't seem big in the show, it just sort of seems like earth ponies are kinda at the bottom of the totem pole and the hybrid ones are at the top.
