I found another interview from 2003 with a brief mention of These Days:

The lyrics on "Everyday" reinforce the message that Bon Jovi has always forwarded as a band, perseverance in the face of adversity...making the best out of a bad situation and coming back stronger.
Jon: We've always tried to find the optimism, and that's what been signature for us throughout the years. Even through a darker record like "These Days" we were feeling rather optimistic, even though at the end of the day when people would bring it up and say, "God this is a dark record, why are you guys so upset?" And I would say "Gee, we're in a great mood" but what has worked for us throughout the 20 years we've been making records is trying to find the optimism in any subject that you write about. You know, if it's "Keep The Faith" after the riots in L.A., or if it's "Everyday" after the World Trade Center" you try to find the optimism. A reason for people to wanna go on.
