TheStreet's Jim Cramer asks, "What do we want from a consumer-packaged-goods company? Are we asking for too much? Should we be content with so many companies that are struggling to grow low-single digits in percentage terms on the top line?

Let's discuss how this impacts income investors," writes Real Money Pro columnist Christopher Versace.
