Those who get money easily will of course find it very difficult to manage it well so for them of course they really need a financial advisor to be able to help them manage their finances well so they don't spend it on things they don't need because if they don't use a financial advisor with their money what they have, of course this will be very unfortunate because it is very difficult for some people to manage their money well and for those who have experience in managing their finances well, it will certainly be easier for them to manage their finances.
A person that have just received inheritance will certainly have hard time for it. But if his dad is too wise at all, he'd be welcomed to his company when he's still young and got taught on how the operations were done.

There is a popular practice in my country among the rich families in which they start teaching their children their line of business at a very tender age to prepare them to take over when they are done with studies. Even though all their heirs might not follow the same line of business, there must be someone to continue the family legacy and such is nurtured from a very young age and trained in school in line with the type of family business. This will ensure the family's wealth is protected and always transferred to the next generation and this practice is the reason some families are always rich from generation to generation.
