Clark wasn't raised as a Kryptonian superhero in red and blue tights called Superman/Kal-El. Ma and Pa and Clark didnt even know he was from Krypton. Clark was raised as a human farmboy in ordinary clothes called Clark. His personality, his wholesome farm-boy outlook and worldview had been shaped thinking of himself as human, with strange abilities, but still a farmboy named Clark Kent, whose identity was solidly formed by his folksy human Kansas parents' values, without any desire to return to Krypton. It makes sense for him to feel human and think of himself as Clark from the farm at heart because of his upbringing, not as a Kryptonian alien Superman/Kal-El. Farmboy Clark is who he is, at heart, courtesy of his upbring. Clark didn't even know of his Kryptonian heritage as he was raised assimilated into Earths Kansas farm culture as a baby. So he wouldn't see Earth from an immigrant perspective or an orphan perspective. He grew up in a very loving household raised by two Earthlings that were parents in every conceivable way. He would actually have a problem trying to understand what being Kryptonian is all about. All he has really known his entire life is Earthlings and Earth culture. Farmboy Clark was the one that was raised by his parents and the glasses wearing Daily Planet Clark was the disguise and in Byrne's Man of Steel farmboy Clark creates the new Clark Kent, which is the Daily Planet Clark, with glasses and his hair slicked back and he stoops a tad, which is a disguise. Farmboy Clark is who he is at heart and Clark created the Superman identity and the new Clark Kent disguise. Farmboy Clark was the "real" person at heart and the Superman identity was a red and blue uniform, a title, a job, a duty, a responsibility. As in the Fleischer series, the disguised Daily Planet Clark Kent in the Rudy Spears series spoke with a higher voice to sound different than Superman but he wasn't a bumbling, clumsy buffoon like Christopher Reeve's. Byrne's Daily Planet Clark Kent was not viewed as a cool guy, Lois generally disliked him. I agree that the Ruby Spears series was definitely trying to be a combination of the past and 1988 present by combining the opening from the George Reeves TV show 'Look! Up in the sky!' etc. with the John Williams Superman movie score and the Byrne/Wolfman corrupt billionaire Luthor, etc.
