Literally hundreds of thousands of dollars. Flights on private jets when there's a pressing need for travel. Rent and food and entertainment in major cities, full tuition payments for millennials and, as they reach the point of starting their own families, their children.

Relatedly, one of my strongly-held, but weakly-sourced opinions is that the disparity between anger about financial inequality (wildly inconsistent throughout the country, but not really dominant anywhere) and the level of actual financial inequality (higher than ever before in the history of the country) is largely due to the fact that most people, like you are realizing here, don't actually see that disparity that much. A lot of this wealth transfer is obfuscated (very deliberately!) and laundered through less-explicit mechanisms, like the aforementioned "paying for the ludicrously expensive nightmare that is childcare".
