Rich is relative, for some people. For example, a person who already has a good job, a high position, a large salary but lacks time for family, decides to leave his job.
He then chose another job which, on the one hand, did not generate as much money as his previous job, but on the other hand he had enough time for his family.
In this way, he actually feels more 'rich' than when he was 'rich'. For him, wealth is happiness – something that can only be felt but cannot be measured in nominal terms. Of course, by definition they are already 'Rich' because they are already in a safe stage to fulfill their basic needs.
But it's not that people like this can't get even richer, they can if they want to. However, they choose to prioritize what is more important in their lives. And for some people, the main thing does not always have to do with money. Because sometimes happiness is also a form of infinite 'wealth'.
