> I'll never understand some people's fetishization with getting darker via tanning though

While some darker skin people want to have lighter skin.

Maybe at some deeper level it’s something about being human. We always want something the other person has

I'm pretty sure it's just cultural. They don't want to be fairer, or darker, they want the social status that it, allegedly, signals.

This. Same with curly vs straight hair.
