Private Company Investments: Over centuries, the most reliable way to create more wealth is the same way most families created wealth in the first instance: starting and investing in private companies. Starting with the Medici and Rothschild families and continuing to Bezos and Walton and Buffett, the greatest dynastic fortunes have been the product of repeatedly starting or investing in private companies. Apart from their proven ability to create wealth, private company investments have added advantages related to taxation and generational wealth transfer – thereby extending the life of the new wealth they create.
