Dude... The US makes up 4% of the global population. Is your US manufactured product, which costs 3x more than an identical Chinese product, going to sell anywhere else in the world simply because it was made in the good ol' US of A?
Come down to Earth, friend.
That's why I said other costs need to be made to push it back towards 50. The numbers I used are rough estimates and easy to mental math versions of the Apple FYI
Products like the iPhone (consumer retail good) wouldn't have much of value added because Westerners like to talk about child labor laws, but not care about where their coffee actually comes from. However, the decreasing of Corporate Tax rate will also serve to maintain the profit margin, as that is primary thing that needs to stay the same. IDK if you're American or not but it's like getting a new car, the only thing that matters is the MSRP and negotiating that lower. All the bells and whistles otherwise are there are a shell game. If a product costs 3x as much to make but laws are put into placed mandated the making of it in the USA and the profit margin stays the same, businesses will give 0 shits. In the end, Trump doesn't give a fuck about other countries and if you don't get an iPhone but he creates more actual American jobs that are middle class and Apple losses some market cap, who the fuck cares? He's not here to serve the global people - he's here to serve the AMERICAN people. period.
I understand how the potential transitioning away from a free trade economy has people up in a tizzy as systems are in place to encourage it. With automation however, we are shifting back towards a protectionist one and the key thing in business is to be the first at it. Apple got it's start as being among the first of consumer retail operating systems, they understand. Free trade has started to become to crab bucket mentality and I don't fault the other crabs err countries for trying to cry and pull us back in. As the #1 economy in the world, we have the leverage to do that. Even the EU/China/Russia/UK/Japan do too, it's just the belief is there that you can not, you just have to have something unique that others will want to buy, that's how Russia stays very relevant given it's mineral extraction enterprises. German and Luxembourg stays relevant in steal manufacturing by making ultra precise and unique pieces, even though the Ruhr valley is a shell of it's former self for resource extraction. Find a niche, and exploit it. Or, have the system in place for that opportunity to grow.
There are other factors in play too like the cost of building the new factory, threat of China shutting down Foxconn early, etc.
Anyone who says moving production to the USA without other regulations/laws being put into place is wrong. Anyone who says it's impossible even with those laws/regulations is also wrong. Serious excise taxes designed to mold the economy used to be a primary income generator for all Western countries, and the fact it's back on the table has people in a huff as we've gone a century where it's only trended away. Shake ups always worry people, just like Obamacare. When something is fucked, a situation needs to be shaken up or you will slowly be strangled to death. Not all shake ups are good, but there are merits here you are missing.
