Not to mention, you cannot predict the future and you might lose your wealth outside your control. wealth is only able to grow if the state and society itself is stable, otherwise you might have worked for naught, and lose everything in the process thanks to war/climate change/economic depression etc anyways. (my SO's family lost all their wealth in world war two for example, and i am talking generational wealth here).

Raising your kids to be able to stand on their own and deal with the harshness of the world is far more important in my opinion.
