I've been in companies that became founder led to professional CEO led, and you can see the difference in how effective a company is. I think there is great shareholder value also in founder led companies too, which have led to the growth of some of the largest and most successful companies in the world. When gates left microsoft was probably the begining of the company becoming somewhat irrellevant. Apple, tesla, epic, facebook, google, etc are all great examples of this.
There is a really great possibility that america shoots it's future economic growth in the foot with something like this, just because it's future superstars companies are not led by their great founders.
