> I knew I was the only poor person at my tech startup because I was the only person who would say hello to the cleaning lady as she meekly made her rounds around us when we worked late. Everyone else had a long habit of ignoring anyone like her. That's IMO the worst behaviour of the rich listed in this article. I've heard stories that at Google, the non-engineering workers at campus may not socialize with engineers…
I'm definitely not poor, and I've always greeted the cleaning staff. That's not a sign of being poor, it's a sign of not being an ass.
Seriously, why wouldn't you talk to the janitor or anyone else? They're the reason you have a clean place to work. I never got the "nothing in common" routine either. They're people, with lives and families and wants and needs. Yeah, they're not spending their day banging their heads against their desks solving reference counting bugs, but they're working to support their lives as best they can.
