It's one of question which differs from person to person. How do you define richness?
In my opinion, being rich is when you no longer have to worry about all the costs of living, rising food prices, rising petrol or electricity prices are no longer obstacles because both your income and investment returns are enough to cover everything, even though the money you have can't live with everything luxury goods, but if you can stay calm with all the inflation that is happening it is wealth.
Also, the investment that I have can guarantee a good life in my old age without having to depend on anyone.
That is true, being rich for doesn't mean you can afford the luxury lifestyle.
But you are not worried about inflation, rising prices and the likes because you can afford to pay without worry.
