In boxing, athletes who do not understand finance are often taken advantage of by their managers. Mike Tyson sued his former manager Don King for $100 million. Today many MMA fighters have disputes with their managers for similar reasons. Its not unheard of for prize fighters who make millions to have funds mishandled by management and money handlers.

In general, the only way for people to not be taken advantage of is to be literate in finance and money and be directly involved in everything. The poor are a prime target for con artists and thieves due to lack of financial literacy. It is sad to say but if people can get away with exploiting lack of knowledge in the poor, or in wealthy athletes, they will often do so.

Even if the poor do succeed in turning a profit. It may simply mean they'll find their favorite drug dealer to buy drugs and spend it all. When COVID stimulus checks were sent, some people literally blew it all on drugs and were poor again within a very short span of time. One issue with poverty is, profits won't necessarily be handled in a way that translates to long term longevity. Impulse shopping, lack of discipline and user credit could all conspire to help the poor remain forever poor.
