Why do the "populars" get so much hate?

[HelloDear<3]

Okay, so I am in no way calling myself pretty, or gorgeous or better than anyone else. In fact, I'm actually pretty insecure. Anyways, my friend Cassie came up to me the other day and we were talking about school and stuff and she said "Oh you're lucky. You're popular." that kind of threw me because I've never really considered myself as popular-I'm just friendly with everyone. So within the next few days, I've been noticing that lots of kids hate the "populars". I mean, i know it's all with the social media and how we precieve populars to be. People expect the popular people to be like Regina from the movie Mean Girls but in fact, they are all really nice. I mean they're popular for a reason right? I just don't like to be hated-I don't think any one likes it! Aren't we over the whole posh, rich, glamorous, bitchy, head cheerleader stereotypes?
