Most wealthy people’s wealth is in investments. If the value of the investments goes down, there are fewer resources to “buy the dip.” It doesn’t hold water as a theory. Basically robbing Peter to pay Paul.
Investors do hold some cash, but they generally prefer not to hold a lot of it because inflation reduces its value. $44B sounds like a lot of money, and it is, but it’s only around 8% of the $632B of assets they hold. (Not sure where you got your much bigger figure; mine is from their consolidated balance sheet reported in their 10-K report for Dec 31, 2024.)
You're comparing apples to oranges.
Net worth is in dollars, while economic output is dollars per unit of time. The comparison does not make sense.
You didn't even say which unit of time! Hell, I have a higher net worth than the total economic output of the US, given a short enough time frame.
It's not pedantry though. It really makes no sense to compare earnings per unit of time to accumulated wealth. They are entirely different things.
Compare the wealth of Elon vs wealth of average person on the Earth, or average US citizen. Those are also mind-boggling numbers and it makes sense to compare them.
