Like I have a choice ? I have apple computers made in the US, as I'm deep in the ecosystem, where do you recommend I turn for my OS? Apple has a choice where they manufacture .
My Japanese gear....mostly Japan thank you. As it consists of photography gear. Majority of my L lenses are from Japan.
You certainly do. If you feel strongly about the societal norms you enjoy in the UK, and rail against governments that are at odds with your views, simply do not buy products manufactured in those countries. Life will go on for you.
Apple has a choice where they manufacture to the extent there is infrastructure available to support Apple's manufacturing requirements. With respect to iPhones, that would be manufacturing 600,000+ iPhones per day on the average, peaking to close to 1 million units per day during certain periods (product release and Christmas season). There is only one country in the world that can support those manufacturing requirements.
Write a letter to Tim Cook making a convincing case that you and millions of others would be willing to pay a lot more money for your iGadgets and perhaps he would move manufacturing to the UK after your country spends many years developing/encouraging the needed infrastructure and training many tens of thousands of people - Foxconn, btw has around 1.2 million employees. Be sure to address in your letter how you would convince Samsung and all of the other electronics/gadget manufacturers to move their manufacturing to western countries so that the cost of their devices will be priced similar to Apples much higher prices, so there is no unfair advantage in pricing.
