Old money is to upper class as upper-middle class is to ?

Old money refers to families or individuals who have inherited wealth and status over many generations, often associated with the upper class. In contrast, the upper-middle class usually consists of professionals and successful business people who have earned their wealth more recently, often through education and hard work. Therefore, if old money is to the upper class, then the upper-middle class is to new money. New money describes those who have recently gained wealth, often through entrepreneurship or careers in industries like technology. For example, a tech entrepreneur who becomes a millionaire after starting a successful company represents new money in the upper-middle class.
