An interesting perspective, but I think it's worse.

"That food court is full of kids hanging out, it brings down the tone, close it."

"Lots of kids on the waterfront today. Time to chase them all off."

"Too many kids in the mall."

Young people, especially if they are not rich and white young people are seen in America as an eyesore and potentially dangerous.

Which is now becoming self fulfulling.

"A kid shot another kid on the waterfront in front of tourists. How do we make sure there are zero local kids on the waterfront in their own city so the rich white tourists feel safe?"

Yes, this is specific, but it's also general. We have made our cities welcoming only to one type of person:

An adult who is, in that very moment, spending money. In that moment.

Kids need stuff to do. They need to not be feared. Teenagers are not an eyesore.

It's broader than "not enough nightlife." It's an entire society where one is permitted to do two things: Earn money and spend it.
