By supply and demand you should get one lambo for 50Usd or maybe Even for Free.
That's the secret but nobody don't talk about it world is over. Supplied there is too many goods but hard to storage them or destroy.
And Even food the world is full of food even good food goes into waste.
And If we look at all those eshops like ebay amazon we have situation when supply is way higher then demand.
There will always be a luxury market for the 1% super rich people of the world. It doesn't matter who holds the cash, because if one person losses it someone else will gain it and take his place spending it. Supply and demand don’t really work for the billionaires of the world, because they want to be different from everybody else. There are limited amounts of Lamborghinis or Ferrari in the world, some models are even only produced in very small numbers. This gives a lot of prestige to the owner of the cars, because everybody knows how expensive they are and you can't afford them from a normal salary. Same goes for the clothes the rich people like to wear. The quality of a T-Shirt or Short will never justify a price of 2,000 USD, but showing a logo to everybody else from such a special brand makes it worth it. Luxury items are never going to be for the masses and we should be fine with it. If you had millions in your bank account and don't care about money anymore, wouldn't also buy the fanciest items in the world? You got to somehow spend your money after setting up your family for life.
The designer shirts are nothing special from other shirts, the brand's logo hikes the price. The rich people wear those shirts to prove they have sufficient money to waste on cheap clothes, sold for a high amount due to the designer's name. In a few months, the clothe gets disposed of as rag. So, no special meaning in wearing those expensive clothes, if not to show off. Celebrities wear it for the music video business. While the super-rich don't patronize such clothes, they easily wear easy-looking clothes. Like the world's richest men, they also appear in cooperate wear to business meetings. Only the luxurious social media influencers wear expensive designers to help promote their page and that of the designer's shop. Other people who spend many luxurious items are the kids of rich men like Op said. But, in most cases, the super-rich rarely go broke to the extent of not falling back rich; their generation being homeless. It never takes a single year to be in the circle or family of 1%, the money is very old and can't diminish without any significant reason.
Take for instance, Big Paul, from the Castellano Family, he happened to be super rich and lived in the most expensive neighborhood in America. He continued his Father's meat butcher business and built more wealth through it. Such people didn't pass any financial disputes, as kids till adulthood.
For that single act, nothing is money to similar people who grew up in such families. They'll easily buy the most expensive cars, houses, and clothes. But, those who didn't grow up wealthy, but ended up rich. Don't easily spend lots of money on fancy things, like their kids would. Another people who spend lots of money on purchasing expensive things are the middle class people claiming to be rich. And, sooner they get poorer, leaving their kids, with no business, property, or job opportunity. Hence, they'll end up homeless like Op said. I think he's referring to the kids of this type of middle-class men.
