There are two thresholds that matter: "rich" is where you no longer have to really think much about money on a day to day basis, and "wealthy" is where you no longer have to work for a living. Both thresholds depend on your expenses and the lifestyle you're looking for, I guess
I was about to type something very similar, but switching words. “Wealthy” to me implies having enough wealth to not really worry. “Rich” makes me think of Lamborghinis and yachts and mountains of cocaine.
I’d be a slight exception… I’m VERY MUCH not rich but I never think about money. I can’t afford a house and I would really love to have my own house…. I don’t buy many things, but when I do, I don’t think about it. I put everything on a credit card that gives me money back and I pay it off every month. I used to put 5USD of gurl in my car, and now I’m very thankful that I don’t think about filling my entire tank or going out for sushi.
