Are you asking why stock of a single company is different from “stock” of the richest country and only superpower on earth?
Also, money is liquid, can be spent immediately. Stock is not liquid, it has to be traded, vested, etc. and given enough stock will tank yje value if too much of it is liquified at once.
Windows is the one where I need an account to install and that spies on me and throws ads in my face, that one?
