So no, Apple is going to move manufacturing to the US with all the costs and downsides, for a policy that can't last.
In 2010, Apple felt like a hardware company obligated to design software. In 2025, they feel like a software company obligated to make hardware. With the DMA/DSA barrelling down the tracks it doesn't really matter where Apple is headquartered - governments will regulate you out of certain behavior. They have to reform their business pretty radically if they want to remain profitable, the old economics can't keep limping along like they used to.
For America to continue to be wealthier than other nations, we can't make the same things that others make. We have to make things others don't know how to make, and charge a premium. That's the way to wealth. Let other countries make t-shirts, sneakers and even cars. Anyone can make those things. We will buy their stuff low and sell our stuff high.
So what should we make and sell for a premium? Boeing airplanes, GE & Pratt & Whitney jet engines, Satellites and aerospace systems, NVIDIA chips, Heavy machinery (e.g., Caterpillar, Deere), Automation and robotics components, Immunotherapy and gene therapy, DNA sequencing and gene editing tools, Implantable devices, Robotic surgery systems (e.g., Intuitive Surgical's da Vinci), Diagnostic imaging machines, Cloud infrastructure and Enterprise software, Hollywood movies, Advanced materials (DuPont, Dow) and so on. In other words, things other countries don't know how to make, or aren't as good as us.
What wee don't want is sweatshops paying peanuts.
