afaik, Miracle Whip has never crossed my threshhold, either before or after I came into grocery-shopping control of my house. No one I've ever known would ever touch it with a 10 foot pole; too sickly sweet.
(I know that *someone* must be eating it, unless Kraft is still paying grocery stores to stock it, like they did when it first came out, but I've never actually seen a jar of it outside of a grocery store shelf. When it was invented during the Depression it was designed to cost significantly less than real mayonaise, but those two products have been pretty much the same price all my life, so price wasn't a reason to buy it. Maybe now it's cheaper again, now that mayo has had a big price hike due to egg shortages. All I know is that after enduring the awful things that were passed off as "food" during the shortage periods during and after WW2, my parents wouldn't ever allow any kind of ersatz "substitute" into our house once the real stuff again became available.)
We didn't eat margarine, either. Mom & Dad didn't trust it. (During the War, "margarine" was usually petroleum jelly dyed yellow. Technically, petroleum jelly is safe to eat in small quantities, but it tastes like exactly what it is.)
