Having $2 billion in assets, invested at the historic average of 7% after inflation, yields $14 million every year. The median household income is about $68k per year. Therefore, the passive income just from having $2 billion of assets comes out to about the full income of 2000 households.

That's the only way I've come up with to visualize massive wealth, as it is so far beyond anything I have experience with. That the closest visualization is the size of a town that could be entirely devoted in perpetuity to the whims of the person with that wealth.
