How?
Get married, have a lot of children, given them a lot of love and positive attention and make sure that they receive a strong Torah education. Teach them Middos Tovos, foster within them a strong connection to the past and to the wider community, show them that life is not about themselves but about making the world a better place and increasing Kavod Shomayim. Show them how special and unique they are and that they have the power to make a difference. Teach them that money is but a vessel not to be hoarded but shared. Generously.
Thereby, you create generational wealth.
