And I don't think it works at all for manufactured goods.
For example, in the 70's or 80's Yamaha came out with their Virago line of motorcycles. They were American style teardrop tank cruisers set to compete directly with Harley-Davidson, except with objectively better engines and lower prices. The only thing Harley had going for it was their trademark engineering mistake. of a single pin crankshaft.
Harley asked the government to step in, the government applied a tariff to motorcycles over...some engine displacement, I think it was 1200ccs or so. Yamaha responded by slightly reducing the cylinder bore to bring it down to 1150cc and made a range of lower end models all the way down to 250cc, none of which qualified for the tariff, and Yamaha is still selling cruisers in the US to this day, meanwhile Harley-Davidson is a popular designer clothing label with a small vestigial powersports division.
