“Why rich people prefer elite schools when most others doesn’t see any wort in it?”
I think the answer to this question - as it is stated - is quite simple, Because “worth” is in a large part relative to what you can easily afford. For a household making $50k a year, almost nothing could make $75k a year “worth it”. For a household earning in the hundreds of thousands, or even millions, a year, the cost of tuition is not really going to move the needle. (Similar for those of somewhat lower income who’ve managed to put full or most tuition in a 529 plan, where spending it won’t impact daily life or long term plans.) It’s just another version of the Nine West vs Gucci handbag, or Leaf vs i8 electric car, or x suburb vs y suburb, etc decisions. Bottom line: “I want it, I can afford it, why not?”
