I am under the impression that you are thinking something like: “Bezos has ~100 billion to spend. If he spends 1 million in X, then he has 1 million less to spend on the rest. But he won’t even get to spend it in his lifetime, so that extra million in X doesn’t change how much he would spend in Y. Therefore, it’s wrong to say that Y will become more available because Bezos spent in X.”.
I don’t think that’s the right way to think about all this. (Warning: oversimplification coming):
Bezos earns some income, say, in a year. Almost all of it will be spent. Most will be invested and not consumed, so it will still increase his net worth, but that demand for stuff is still there, affecting the economy. Bezos is already probably spending about as much as he can, and what he is not spending he is saving which probably means transferring it to someone else who will spend it. So, if he spends USD 10 in X, it’s reasonable imho to “expect” the economy to get USD 10 less spending in non-X stuff (on avg)
Yeah, I wasn’t trying to be tautological.
