Jones said Michael grew up with few memories of his father, only Bella’s anger at how Jerry left them.In many ways, I think that a comic book company's ownership and continual renewal of a character is very stifling and unimaginitive. However, with a character like Superman, and a creator like Jerry Siegel, it really does seem like the right thing happened in this case.
Jones said, according to Michael, Jerry “never tried to see me. He never asked about me even when he had to talk to my mother. And after the first few months, he didn't pay a cent of alimony or child support."
Gerard Jones (interviewed in the article for his book) makes a comparison between Jerry Siegel's creation and his son:
“Partly to make up for my earlier mischaracterization of Mike, and also because it creates an intriguing contrast between father and son Siegels,” said Jones. “Michael Siegel grew up to be an athlete and a community volunteer, winning Tae Kwon Do competitions and coaching a youth Tae Kwon Do team for the Cleveland Heights-University Heights Board of Education.One interesting thing is, Michael grew up to be a plumber. In Alan Moore's "Whatever Happened to the Man of Tomorrow" (a story about the end of Superman), Superman also ends up as a plumber. Probably a coincidence, but interesting anyway.
At any rate, Jones's book Men Of Tomorrow sounds like it'd be an interesting read.
