Americans seem to think they have everything it takes to produce iPhones in the US. Well surprise: they don't. China has become the factory of the world and they offer far more than just cheap labor. They have all the know-how, automated factories, weak environmental and social regulations, ... And by producing everything in China we're not only handing them over our cash, but also our knowledge. In return, China is purchasing Africa because that's where the real cheap labor and natural resources are.
This whole Trump-US-narative is so behind the times and out of touch with reality, it's not funny anymore. We live in a globalised world with multinationals having more money and power than governments. They dictate the agenda and the only thing that counts is profits. Because we, the consumer, ask cheap things.
Meanwhile, corporations pay almost no taxes, and decide in a wink to move a plant to the other side of the world. And countries are forced to compete by offering even lower taxes and weaker regulations.
Maybe, I'm being naive but at least Apple is one of the few corporations that tries to do the right thing in many regards and I feel it's more than window dressing. They stand up for equal rights, invest in green energy and have a roadmap to avoid some chemicals. But make no mistake, the business there in is very polluting and as long as there's gold and cobalt among other things in their devices, their products will be a social and environmental disaster. Just like the products of the competition. But at least they try to minimise some effects.
But whether the final assembly is done in China or the US doesn't make any difference.
