It's one of question which differs from person to person. How do you define richness?
Being rich is when you can cater to all your needs and wants without compromising your funds. When you are ready to help other people in need, most especially in their financial problems. And being rich is when you don't worry your future anymore since you have reserved adequate funds to create a brighter and a more meaningful future. And once you're rich, you become financially secured and independent that no matter how many problems you might encounter, you will always be the last man standing.
Some might say those who can fulfill all of their desires are rich or those who don't feel the lack of funds inflow for these financial needs are rich. It depends on the individual's personality and social standing. From my prospective perspective, someone who is knowledgeable and aware of most of the history of the world and society is rich. His knowledge and personality represent his richness.
You can never be financially secure and independent as human desire has no limit and money can not fill its desire. Some people feel insecure by thinking about how he will feed his family while others feel insecure if they can not buy the latest model of the iPhone by thinking his social status will drop. This whole thing is sentimental and can be totally different for every human being.
