I think selfie sticks are more indicative that no one trusts anyone anymore. When I was a kid on holiday we used to ask strangers to take a photo of is as a family so my mum could be in the picture as she was always the one taking them. We would hand over the camera, pose and then have a lovely photo of the 4 of us.
No one wants to hand over their iPhone to a stranger to take a photo. Cod obviously the stranger is going to run off with it. Because the world is run by greed and everyone is evil.
Selfie sticks are just another nod to our increasingly isolated society, every man for himself. We don't ask other people to help us anymore because we assume they won't. So we invent things which mean we don't need to depend on anyone else and society continues to dissolve.
