The first movie was very careful not to actually say anything, especially without any conviction.
You took the message that it was about how society beats poor people down, chids thought it was a movie about how unfairly men are treated in modern society, people with mental health issues thought it was about how the system failed them.
No solutions are given to any of these vaguely referenced issues and if the King of Comedy didn't exist I'm not sure they could have actually come up with an ending to this movie because they might have had to actually resolve any of those themes.
