My 2006 T100 was a "J" stamped Bonnie, assembled in the UK.
But the forged crank flywheel had "Made In Japan" embossed on it.
The whole question about - what does it mean to say made in the UK or the USA is really irrelevant.
Globalization has made it a moot point - the pendulum will never swing back to the West again.
Reduced manufacturing costs, and raw materials, lack of enforced environmental regs, low taxes, and government controlled unions make Asia the manufacturing site of first preference for companies, and financial institutions.
Startups have to go to Wall Street financial institutions for their investment cash. These institutions evaluate the startup's chances of success. If good, they receive their cash at favorable terms. The lower the evaluation, the less likely that startup is of receiving its requested amount, or favorable terms.
If that company decides to manufacture in China, or another Asian nation, they are far more likely to get favorable term from lenders. Wall Street has been part of the whole de-industrialization in the US for nearly 30 years. They show no intent to change this behavior, why should they, they're making money by the boat load.
Americans like to buy cheap throw-away s**t, so we all have a responsibility for this too.
