Yea, a difficult economic situation can impact a billionaire negatively and even reduce his financial power significantly, just as the case of aliko dangote, he was once the richest man in Africa,
Aliko dangote is a perfect example for this topic because of what the current state of the economy is doing to his business, actually if somebody should tell me that the economy will impact negatively to him this way I would be very skeptical about it because the person in question is a billionaire who is on the world record of the richest people and now his wealth has dropped massively because of what the country is going through and it will take a very long time for him to bounce back as before, so actually bad economy can hardly broken a billionaire but it will definitely affect them negatively in a way they will never imagine.
