This character is a NEET.
NEET is a government initialism for people currently "Not in Education, Employment, or Training". NEET classification comprises people who are unemployed, not engaged in housework, not enrolled in school or work-related training, and not seeking work. The "NEET group" is not a uniform set of individuals. It includes those people who will be NEET for a short time while testing out a variety of opportunities, and those who have major and often multiple mental disorders and are likely to be NEET for most of their lives.
This trait does not apply to people that are very rich and have no need to worry about earning income for the rest of their lives.
