There are people who are so Wealthy then they made all things possible to change their stories, have all forms of investment and businesses but guess what? Their children couldn't sustain the wealth. So first as a man before choosing to make your wealth also try to teach them how to preserved wealth I think that is the most difficult place were many known businesses has folded up even some we don't hear about their names anymore is because of lack preservation. I can say creation is a bit easier but where the problems lies is to sustain it and pass it up to the next generation which would happened to the third generation and watch carefully those who were able to sustain their wealth continually even to the next generation were thought on how to preserved and diversify their wealth.
I think the first thing you should do is make the wealth. You most likely start making the weather before you give birth to the children or before the children are old enough to understand money. It's good to teach your children how to preserve wealth, but most times it's not because the children do not know how to preserve wealth that's why they ran the business to the ground.
Sometimes it could be harsher economic conditions. We know factors in this time that are advantages to businesses but there are also disadvantages like more connections, inflation and unemployment which means less purchasing power.
The business may be a business that's bumming in the parent's time, but not so much in modern day. Take for example a company that manufactures radio set or newspapers.
What about kids that do not want to follow in the footsteps of their parents? The parents are in oil for example but they want to do something else, like go into sports. Everybody wants to make a name for themselves.
So I believe you should make the wealth and teach your kids not just how to maintain wealth but how to also make wealth too. This way in whatever field and time they find themselves, they will be able to adapt and succeed.
