Regarding A): Exactly! I don’t really mind traveling together with people from my own class (I might even prefer it), but I don’t really want to travel with lower class people. That just makes me feel like I’m one of them.

I think this attitude is quite common, but people won’t admit it. I would never admit it like I just did if I didn’t have an anonymous account. And I don’t see how technology will change this basic preference.
