He's just a noveau riche, he can have as much money he wants but he don't have the entrenched position and that entire root system of connections they have which gives them real power.

The Rothschilds collectively are the wealthiest in the world that we know about, excluding figurehead royalty due to disputes on what they actually own and how to separate them from the state.

One important thing to know is that wealth isn't publicly listed anywhere. The vast majority of it is self reported. Sure if you own enough stock as a percentage of a company's total you get publicly listed, and theoretically if you're stupid your real assets are in your name, but that isnt how wealth is held. Wealth is held in private corporations, estates, and trusts, layers of them. It's why the wealthy can avoid taxes in the first place, there is no accurate measure of it all.

Those Forbes lists, for example? Entirely self reported, famously so as that's how Trump was ever listed as a billionaire despite (best reporting and federal investigations showing) him never having any combination of assets that could be totaled near a billion.

The real people with the real wealth, not tech bros with overvalued stock, don't have assets directly attributable to them anymore, they learned their lesson back when American workers fought the US military for basic workers rights and Russian workers were beheading tsars.
