When did infrastructure become so popular among Democrats?

[Tartarus Sauce]

Places that experience population decreases should not expect to continue maintaining everything, "managed decline" often makes more financial and practical sense, and this is the case across large portions of the United States, especially Rust Belt cities.

I'm nitpicking here and this is besides the main point you've been making throughout the thread, but I must contend that "managed" is not a particularly accurate descriptor for the decline experienced in the Rust Belt cities.
