It depends on who "you" is. I got a buddy that worked years ago as a movie stunt man. He still gets checks in the mail.
Democrats love to refer to dividends and interest as "unearned" or "passive" income. That may be true for Kennedy and Heinz, but those leeches live off our taxes. People who actually make a living with interest and dividends have to work pretty hard to get things set up enough to make a profit.
Please don't misunderstand me - I'm no Democrat!! I'm just using the terms in the same way the tax code and Social Security Administration do.
The point is that when one has an investment in a productive asset, whether it be a stock portfolio or a manufacturing facility, that asset is what creates the wealth. Couldn't we say that the ongoing use of your friend's work in the product of the film was what created his stream of earnings?
Similarly, when the world was in upheaval from 1939 - 1945, everybody looked to the US and its productive capacity to be the the "arsenal of democracy". If we abandon "production" in favor of "services", we cannot fulfill this role and, with some limited exceptions like the one you pointed out, the wealth dries up.
