Not to mention no one is investing in manufacturing if the economic conditions to support it get changed every day or two.
Which is the biggest flaw in all this. If the goal was to bring consumer electronics manufacturing back to the US, adding a tariff that goes up every quarter would make sense. People could make plans and build factories. YC might even fund something.
Trump doesn't have the authority to set permanent tariffs. All this is being done as a temporary measure under the Emergency Economic Powers Act, which is for wars. These backdoor tariffs are being challenged in court, and there's a good chance of the plaintiffs winning.[1]
For tariffs to stick, Congress has to do it. The Constitution gives Congress sole power over tariffs. There's a long-term track on this, going through the US Trade Representative's office, with Federal Register notices and public comments. Last week Greer was up on Capitol Hill testifying before a congressional committee. That's the normal path by which tariff changes are made. Greer is so out of the loop that he hadn't been told about the big tariff on China. That change came out while he was in front of the committee. He was publicly humiliated. Which means he can't do his job of negotiating with other countries on behalf of the US. Greer may quit.
When you dig into this, you don't find "4D chess".
