Managing decline is not a plan for survival. No matter what you think of Trump, this was one of his primary policy issues, and is the basis for the "Make America Great Again" slogan.
The creedo has a more specific and probably incorrect message: " we are broken, we need to be fixed. (Implied) I'll fix things". It's easy to attract conservative minded people as a rally cry to your cause when you reach for a nostalgic rhetoric about "the good ol' days" fallacy. Much divergent from the often left leaning "we can build a better future" which should probably also be considered a fallacy.
Back on topic, I don't think the electioneering slogan had any actual policy significance.
