So you're saying his assumption is incorrect because you want something else? You should read some of this guys other stuff - a point he's made many times is that most disagreements in financial advice come from "people with different experiences in life, different time horizons, different risk tolerances talking over each other". There's a lesson in there for you. You don't want to work at your grandpa's company, fine. This advice may not be for you then. That doesn't make his premise any more flawed than your own. And FWIW a thousand year old company does not require that it stay within the same family - which is from your (flawed) assumption. In your own example of "creating a business, making a profit, and handing down wealth to your family", one of the ways to make that profit is to sell your business to someone else, who may sell it to another (on and on for... a thousand years). So not only are you claiming he's wrong based on an opinion you have, your opinion isn't even contradictory to the point he's making.
