I mean that's definitely cherry picking portions of the wiki. Both of the articles refer to each other much more than those examples, not that that really matters.

Plus the Supply Side Economics wiki article, right below the "Not to be confused with trickle-down economics", contains a huge box pointing out the many issues with the article, including but not limited to "Needs more academic or scholarly research, rather than newspaper articles." and "contains weasel words: vague phrasing that often accompanies biased or unverifiable information."

I also was trying to google it and saw what the other commenter saw btw. The AI overview on Google says "Yes, they refer to the same core economic concept, but supply-side economics is the formal, academic term, while trickle-down economics is a popular and critical label for it. Both argue that cutting taxes and reducing rules for businesses and rich people will help the whole economy". And it references: https://mattbruenig.com/2013/01/07/on-trickle-down-economics... https://en.wikipedia.org/wiki/Trickle-down_economics https://study.com/learn/lesson/video/demand-side-vs-supply-s... https://www.annenbergclassroom.org/glossary_term/supply-side...
