Making a lot of money doesn't teach you money management skills. A lot of these players are poor kids that go to college and then the NBA and don't have to earn their own living in between all that. I learned how to manage money when I moved out of my parents house and got my own job and place. I had to take care of myself and manage my own funds.
Many of these players don't experience that.
I also believe it's a cultural thing. cacs (especially jews) and asians are all about generational wealth and passing that shyt down
But due to slavery,jim crow and widespread poverty in the black community, we never really developed that way of thinking as part of our culture
A person who's on a mission to build generational wealth would never throw it all away
