Being able to live the lifestyle you want without having to work is my definition of rich. A homeless person, who is homeless by choice (there are some) may be rich.
A family that can afford to have one or both parents home without working is rich. But, I’d like to caveat that by saying I bet they work hard at managing their finances. If I wanted to move to the mid-west or southeast I could probably afford to not work anymore…but I choose to live in LA and must work to afford my lifestyle. I make a handsome living, but do not consider myself rich.
