Not to swerve off the rails to politics again, but for those old enough to remember, Reaganomics was the era of so-called trickle down
Trickle-down economics, or “trickle-down theory,” states that tax breaks and benefits for corporations and the wealthy will trickle down to everyone else
No need for politics. But what you left out was that “trickle down” was a derogatory term created used by the critics of Reagan tax cuts.
So the intersection of the set of people who use the term “trickle down” and the set of people who agreed with Reagan’s economic policies is pretty much an empty set. Anybody who says “Trickle down economics works” is a common saying sounds like they’re pushing alternative facts to me. Regardless of whether you agree or disagree with the economic policy, “trickle down” was a term used by critics, not supporters.
ETA: Upon fact-checking myself, the term “trickle down” is much older than the 1980s. But wikipedia agrees with my primary point, that it’s always been a derogatory, critical nomenclature, not a supportive one, and even presents some evidence that it’s an intentional mischaracterization.
I've only been following politics closely for less than a decade, and I thought that "Reaganomics" and "trickle down economics" were synonyms for each other without a difference between them.
