This is false. Pretty much all personal income is taxed, and definitively dividends. While it might be beneficial for the society to tax assets, any personal income from those assets are taxed in most cases. There are ways to avoid it to a certain extend but if you want a 5 million euros from one of your companies you would pay tax on that. If you want a boat you could set up HireMyBoat Inc and then avoid paying taxes on that 5 mill to pay a boat but still use the boat for vacations (this might be illegal but very rarely enforced).
