Linda Holmes at NPR did a deep dive on 'Ya Got Trouble" from The Music Man back in 2014 (which she notes was written in 1957 and set in 1912):
It's just worth taking a moment now and then to remember that people have long believed the culture was collapsing, the world was going dark, the music was all junk, the books were all corrupting, and the new thing replacing the old thing meant the new people were going to be worse. And that panic has always been built in the same ways, and always used to motivate people to do things and spend money and join causes.
And ragtime! Shameless music that will grab your son, your daughter in the arms of a jungle animal instinct.
Well, it wouldn't be a classic cultural panic without a little appeal to racism about a genre of music that originated in black communities and how it's going to bring out the out-of-control, sex-having jungle animal in your nice little kids (including daughters, mentioned here for the first and only time during a rant that's been mostly about boys).
And then he yells:
He just told them he's inducing mass hysteria, but that's okay — they're not listening.
“But that’s okay—they’re not listening.” It always is as it always was.
