When DC confirmed Superman would be revealing his true identity to the world, it's safe to say it divided the fanbase. Some felt the secret that Clark Kent was hiding should have been maintained, honoring decades of lore regarding the iconic character in pop culture, while others felt it was a move in the right direction.
After all, Superman was all about truth, justice and a better tomorrow, so it did seem like him being honest would help to create, not just a better America, but a better world. It was meant to inspire people, so ultimately, the intention was great. However, with the publisher planning to now retract this and make his identity secret again, there's one issue that needs addressing - Clark has to find a new job.
Superman Being a Reporter Would Be Hypocrisy
No matter what, Clark can't go back to lying to the masses. He came clean about his identity partially because he felt dishonest while infiltrating places as a reporter and then writing stories about himself. It also made Lois come off as unprofessional, as she had access to unique inside info regarding other heroes and villains. Simply put, it gave them both an advantage that made their journalism unethical and took credibility away from the Daily Planet.
Thus, to put Clark back as a reporter would be a repeat of a controversial double standard. It would also negate the emotional connection to the reader. It would be hard to root for a Man of Steel who can't keep his word. In short, the double standard has to be removed, with Kal-El finding another job. This helps remove Clark as an agent of what villains like Lex Luthor would construe as biased, political propaganda on the front page. This isn't without risk of course as it opens the Super-family up to more smear campaigns, but it is morally right.
Superman Should A Working Class Hero
Now, apart from maintaining his integrity, DC can look to the humanity of the New 52 and All-Star Superman, putting Clark with the working class: whether it be a construction worker or a sanitation engineer. These sorts of jobs would fit his powers, as he gets to literally clean up Metropolis or build society back. More so, Clark would be with the common man, experiencing humanity in a "salt of the Earth" light that journalism only affords in select cases.
This way, Clark gets to truly spend time with the people on the ground, becoming the foundation of this better world he wants to see. In the process, DC could help remove the stigma of these professions being "menial," by showing that they are some of the world's greatest heroes too, propping society up in ways we often ignore. The new journey can even go the Superman & Lois route with Clark as a football coach, whether it be in Metropolis or Smallville, making his own schedule to then take out enemies. But what's for sure, the new career can't be journalism because Clark has to stand on a code and principles that paint him as a virtuous figure.
