That's funny because the ones sold on my street are $10 and they definitely have the rayban logo
They account for 30% of the global market. They own key brands, license key premium names, and control key distributors like sunglass hut and LensCrafters.
Their cost to manufacture vs sale price shows a clear ability to price like a monopoly. As does their ability to box out competitors.
The $10 look alikes are not identical. They generally are cheaper materials, not polarized or coated, etc.
No, it doesn't. It shows there exists demand for their products at that price point.
>As does their ability to box out competitors.
They have none. Anyone can go to various websites and order cheaper sunglasses that work just as well, or go to Costco and buy them for $25.
Again, you are getting confused by branding vs monopoly. They sell luxury goods and can mark them at wild premiums, same as Hermès and Ferrari. None of them are monopolies. Very far from it.
