When young people see how these wealthy people live on social media, they developa sense of rebellion, rejection, and hatred for the reality they live in.
People who are truly wealthy do not live expose their lavish lifestyle on social media, many of them do not even have a social media presence, except when they are promoting their business or introducing a new idea that would make them richer and more powerful.
That said, there are some rich people who expose some of their lifestyle on social media, but i can assure you that many of them are not as rich as you think, they are only trying to look rich and they definitely aren't accumulating generational wealth with such an attitude as that. What should motivate young people is seeing how the wealthy grow businesses and how they excel in their field, either in investing, businesses, technology, etc.
