If that were true, people would speak with their wallets. The reality is that everybody feigns patriotism (rah rah!) until they look at the price tag and then they'll grumble and moan but buy the cheaper product, made in China, anyway. That's exactly how we got here unfortunately
Look how many people on here justify buying cheap Chinese tires, TIRES of all things! If there was a Chinese oil that was cheaper than Supertech, they'd be all over that too.
The reality is that many companies did "have a go" at trying to keep manufacturing onshore but were undercut by those that offshored. That wouldn't be an issue if consumers took that into account with their buying habits, but that wasn't how it played out and so here we are. Now, the list of companies that have maintained first world manufacturing is almost totally occupied by premium brands whose prices are out of reach, or perceived as such, for Average Joe. Miele, Bryston, Wolf, McIntosh...etc.
Heck, even the firearms scene, Chinese guns and optics became popular, look at Norinco. Remington went bankrupt and first world optics cost a fortune. My made in Japan scope cost more than many of our more frugal members would spend on a car. Leupold is one of the few, if not the only American optics manufacturer left with USA-made scopes in the "reasonable" price class.
Look at how many folks fawn over the deals at Harbour Freight.
Like green ideologues, the anti-offshoring movement runs into many of the same or same type of massive obstacles. Chinese batteries and solar panels for example, just like oil is so heavily integrated into every aspect of our lives, so is Chinese manufacturing. Folks using TikTok, Huawei ISP and telecom gear, it's easy to see as insidious.
