Donald Trump confounded The Economist when he claimed during an interview with the magazine that he came up with the phrase "priming the pump" — a popular economic metaphor that predates his birth.
The US President was discussing how he's OK with his plan to reduce taxes increasing the deficit in the short term, because it would increase revenue over time.
This was the exchange:
Mr Trump: We have to prime the pump.
The Economist: It's very Keynesian.
Mr Trump: We're the highest-taxed nation in the world. Have you heard that expression before, for this particular type of an event?
The Economist: Priming the pump?
Mr Trump: Yeah, have you heard it?
The Economist: Yes.
Mr Trump: Have you heard that expression used before? Because I haven't heard it. I mean, I just ... I came up with it a couple of days ago and I thought it was good. It's what you have to do.
The Economist: It's...
Mr Trump: Yeah, what you have to do is you have to put something in before you can get something out.
Eyebrows were raised at Mr Trump's suggestion that he came up with the phrase a couple days ago because
It's an old and common phrase
It's probably not the sort of metaphor you'd come up with in modern society
Oh, and Mr Trump himself has used the phrase before. "Sometimes you have to prime the pump," he told Time magazine in an interview last year.
