Living in London and working in the City so long really skewed my view on this. I guess because I worked with so many people earning six figures (and double that for household income) who were still very much "workers", were paying off the mortgage and hated commuting like anyone else. They didn't seem rich to me. Maybe if they sold up and moved out of town, sure, but just trying to live day to day they were counting the cost like an average person just up-scaled.

I feel like being able to live off passive income / interest AND living where you want is where "rich" starts for me. I could live off passive income now, in a basic place far from London but I'm not "rich". I can live pretty much where I want in London, but I'd have to continually work for it. Being able to do either of these things would put me in many people's "rich" bracket but for me it's when you can do both at the same time.
