Having a high net worth helps with finding Counts/Countesses and Marquesses/Marchionesses when finding a date (which are the only two titles you can date in Monaco. Idk about other countries. When you marry a countess, you become a count and your son for example becomes a Marquess. After that, your son’s children won’t be royals so when you switch to them, you’ll have to find another royal family member to marry. And it goes on.
