Yes. (Bought by the same kind of idiots who buy 6- and 7-figure wristwatches.)
Regarding the simple addition of bling:
Musical instruments usually have a very strong correlation between tangible quality and price. Most accomplished professionals play pretty high-quality stuff.
But some instruments (like guitars) sell in very large numbers to casual amateurs who, if they have tons of money and want to go all out, can find manufacturers who will be happy to add some ridiculously expensive, useless options.
A friend of mine used to go to guitar company websites which have online tools for the customer to specify options, and see how expensive a guitar he could design by adding high-end baubles (wood that violates international laws, gold-plated pickguard, acres of mother-of-pearl, etc.) Because the results looked like a guitar a dictator would own, he gave them names like Martin Strongman, Taylor Despot, etc.
The other hilarious thing is that you can get a big bag of the exact same stuff for pennies on the haute cuisine dollar if you go to an Indian (or Nepali, Pakistani, etc.) grocery store.
Try dry-roasted macadamia nut butter, preferably with only a little salt added.
A lot more expensive than peanut butter, but a lot nicer. 
Yeah, I once had a customer ask me if the Pink Himalayan Salt was pure salt. No, pure salt is white. It’s the impurities that make this stuff pink
Great, 84 trace elements - that’s what, 90% of the naturally occurring on Earth periodic table? Funny how they list the impurities that might have some use to you and ignore all the toxic and/or radioactive ones. Granted, the beryllium, arsenic, cadmium, antimony, mercury, polonium, radium, thorium, uranium, and plutonium are in vanishingly small amounts but I find it hilarious that people who are so concerned about “organic” produce, food purity, anti-GMO, and terrified of toxins are willingly consuming pink salt.
Spatulas! Why, I bet the most expensive spatula in Spatula City only costs a few bucks.
You mean they don’t have titanium and platinum spatulas with gold-inlaid handles? What a useless place! :D
McDonalds.
Rich kids, poor kids. They all want to go to it.
I’ve seen kids birthday parties where they rent limos to take the kids to - a McDonalds.
Also kids toys in general. From Hot Wheels to Barbie to Fisher Price playsets to board games to backyard trampolines to Xbox most kids pretty much want the same stuff. This is coming from someone who does kids birthday parties. Most kids want pretty much the same stuff.
Except American Girls dolls. Those are crazy expensive.
Five Guys, Shake Shack, In-N-Out, Smashburger, Whataburger
Shivs.
Ketchup. There are a million varieties of fancy mustard, but not really ketchup. According to a fairly well-known Malcolm Gladwell article, it’s because the sweet, salty and acidic flavors of ordinary ketchup are already in perfect balance, crating a whole more than the sum of its parts, and can’t really be improved upon. Or something like that, don’t feel like re-reading the article but here it is:
I’ve been to restaurants with “fancier” ketchup and they were always objectively worse than good old Heinz.
There are plenty of upscale tacos out there, including this silly $25,000 one.
Spatulas may be cheap, but my private chef is not.
Until Martha Stewart went to prison. 
Want a fancy phone? Try these guys.
Though I’d argue there are 3 tiers of stuff:
- Regular-people stuff.
- Fancier stuff that may offer some value but also may just be nifty and/or pandering to the label-conscious - for those who have a bit more than middle-class income but would not qualify as “rich”
- Rich people stuff
Dyson fans, and Lexus cars, would fall into category 2. A 20 dollar box fan or 30 dollar oscillating fan would do the job, as would a Ford compact car. Things in the second category may offer some bells and whistles above the first but aren’t really game-changers in terms of function.
Category 3, though, is for people who have either “more dollars than sense (cents)”, or have very specific performance requirements.
As for fancy TV sets, I just checked Best Buy’s website; the biggest (98") 8K TVs were tens of thousands of dollars (I think $60,000). And at that level, you don’t just buy the TV and put it on the end table; you’re setting up a whole system, with speakers, AV receiver and so forth and probably in a room furnished as a home theater. Such things can cost hundreds of thousands of dollars.
And no, there’s no such thing as a rich person version of an electric fan, because they don’t buy them. They use airconditioning instead.
