This meme first got really big in central-banking circles after the 2008 crash. Japan has been following this model for 35-40 years of managed-decline. The US has been toying with the same model for more like 10-15 years than 2-3 suggested above.
The US so far has managed its decline better, but not for nothing has "abundance agenda" become a meme lately even on the left -- as more and more people sense that managing the decline is the goal of current policy and they don't actually want to decline.
Back on topic, I don't think the electioneering slogan had any actual policy significance.
And revanchism is? What Trump was trying to make happen "again" wasn't all that great the first time, except for those at the very top.
Do you happen to know how they managed that decline without worse consequences?
