answer:The human condition is “struggling to make ends meet” in one way or another. I’m sure Bill Gates and Warren Buffett have the problem of finding enough time to complete all of the things that they want to accomplish, so that’s the limiting resource for them. For the rest of us, it’s probably a combination of money and time, and for some it’s just money – or something else entirely. But these days, with the economy facing more trouble than usual (since it always faces “some” trouble), it’s a convenient hook to assume that people are cash-limited.
