What? Can you explain you basis for thinking this?
Any wealth the latter two kids have is very much in the nature of temporary wealth that'll dry up in an instant. Neither have any sort of long term contractual security, neither presently have any job/direct income, and they ain't worth more than peanuts playing overseas right now.
And Lavar's "Big Baller" thing ain't the kind of company that's built to last, instead it's the sort of fly by night operation that tends to collapse just as fast as it rose.
The whole company was founded on the premise that his sons were the stars of the future, and thus it would be cool for kids to wear their products. Well, that myth is already being exposed as bullshit. Lonzo's a disappointment for the Lakers. The middle kid is a dud who'll never play college ball or in the NBA. And, although it's still too early to tell with the third kid, the fact that he'll never play college ball and won't be eligible for the draft for years ain't a good sign.
Once the Ball boys stop being a cool thing for kids to emulate, Bill Baller Brand will collapse like a house of cards.
