Whatever happened to the parents?

I did see on Facebook earlier today, a comment about "Popeye and Son", and the comment stated that cartoons designed for children had no depictions of sexual implications during the 1970s and 1980s. Since they couldn't use offspring, they used nieces and nephews instead. I guess that could explain the absence of parents on "The Little Rascals" cartoon spinoff series (kids going on adventures without any parents involved, let alone no parental consent), and the absence of the parents of the Teen Angels on "Captain Caveman and the Teen Angels" - could this imply that the Teen Angels could have had ages ranging from 14 to 16? Taffy Dare and Dee Dee Skyes were likely no younger than 16, as they were old enough to drive (they did take turns driving the van in the series), but Brenda never drove at any time, implying she may have been 14 or 15.

I am getting a feeling that Popeye and Olive's son, Junior, was likely adopted, and that would make sense, since Junior had no resemblance to Popeye.

However, there is one exception to the "no parents" trend - Richie Rich is the son of parents of Richard, Sr. and Regina Rich, who were also seen in some episodes of the series. They were seen together rarely, but on many occasions, only one of the parents would appear. Could Richie's parents have been allowed in his corresponding series because he was nearly a teen in the cartoon series, unlike in the comic book series? Of course, Reggie's and Gloria's parents were never seen, and they made no mention of any or both of their parents.

The parents of Daphne Blake were seen in "No Thanks, Masked Manx" on "The New Scooby and Scrappy-Doo Show" in 1983. Could this imply that Daphne and Shaggy were young adults in that series, despite that they were referred to as kids in some episodes?
