That said, I personally define rich as being part of the capital class rather than the worker class. My perspective (note that some of these are a bit hand-wavy since the levels of money needed sometimes differ significantly and sometimes the lines are not clearly delineated):
- You don't sit on a commercial airplane. You own your own plane or take charters. Slightly lower on the totem pole is taking commuter jets (something akin to semi-charters).
- You typically/often don't drive a car for the purpose of transportation. Someone drives you. That said, you may own one or more cars. Some of these cars may not even be street legal, but they can be delivered to the track for times that you want to take them out for a spin.
- You do, in fact, listen to better music than most people. This might be in the form of live music. It might be in the form of a very well-designed high end music system in a listening room -- music you thought you knew well will sound completely different.
- You don't actually need to use the internet -- for the most part, you have people do those things for you. That said, if you need fast internet, you will probably live in an area that can accommodate your needs (depending on where you live in the US, access to fast internet is not a given even if you have the money).
- Any "work" that is done is done because it is an interesting problem to work on. Other than that, there is very real unofficial work of building and maintaining social capital. Sometimes this is the ugly kind of social climbing that is dramatized on TV. Other (often?) times, it is cultivating relationships and having experiences with people you like somewhere between a little and a lot (more time with the latter). Since money and (to a lesser extent) time are not limiting factors, incredible experiences can be had.
- Most things that people would consider "chores" are not a necessary part of your everyday life. No grocery shopping. No carpooling. No cooking. No restricted schedule due to child care (nanny almost always available).
Those a just a few things that I think are or can be different/better for people in the capital class. Some things that are worse is that often times folks born into the capital class have existential crises. Avoiding this type of crisis comes down to good parenting (and perhaps good parenting advisers and nannies).
Just my 2 cents...
