Ray-Ban is already made in China.
As is basically every major manufacturers products.
They like to claim its designed or engineered in the US, but they send their IP over to china for the manufacturing process and then import and charge you basically what it would cost to make in the US.
The chinese almost always steal the IP and make the product under some nonsense brand name though and they sell it for a fraction of the price. A lot of times the chinese version is basically indistinguishable from the original product, although shortcuts and cheaper raw materials are used to cut cost on the product internals. The bulk of the cost savings largely comes from the massive scale of product.
In a lot of cases it makes more sense to by the chinese version of shit since it all comes from the same source.
I guess I have vintage ones the original I bought in 1989, and one from eBay, 5022 both “made in Italy”
Guess all things turn to shit.
