Epictetus ran his school for the last forty years of his life at Nicopolis, on the Greek side of the Adriatic. He taught there because Rome would not have him.

Domitian’s edict of 89 cleared philosophers off the Italian peninsula, and he went with the rest of them. He had been born a slave in Phrygia. Freedom reached him as a gift from an owner, the standing to teach came from a city, and men he would never meet could withdraw both.

So he built on the one thing nobody was licensing.

If your assembly sits in Binh Duong or Bac Ninh, you learned what you had built on at 12.01am Eastern on 24 July. That was the minute the United States began collecting a new Section 301 duty across sixty economies, priced on whether each one enforces a ban on goods made with forced labour.

Vietnam and Thailand were assessed at 12.5 percent. Malaysia, Indonesia, Cambodia and India came in at 10.

That is the third rate your shipments have carried in twelve months, under the third law. A 20 percent framework rate took effect in August 2025. The Supreme Court struck down the emergency authority it rested on in February, dropping you to a flat 10 percent, and that expired at midnight on 23 July.

You have not moved a machine in any of those twelve months.

You moved them in 2022, out of Dongguan, for one reason that fit on a slide. Assembling in Vietnam skipped the China rate, and the gap paid for the relocation, the new hires, and the two years of yield problems that followed.

The gap was never yours.

The gap was never yours.

Rusticus lent Marcus Aurelius the discourses of Epictetus out of his own collection, and Marcus thanked him for it in the first book he wrote. Seven books later he set down the image the whole practice turns on. “The mind which is free from passions is a citadel,” he wrote, “for man has nothing more secure to which he can fly for refuge and for the future be inexpugnable.”

The walls in that sentence enclose your judgment. Everything you can be invoiced for stands outside them.

So the duty asks a narrow and unpleasant question. Take the gap away and count what is still standing inside.

Across the region the answer runs thin. China’s exports to the United States fell 16 percent in the first quarter of 2026 while its exports to Southeast Asia rose 20 percent, which is the sound of the same components arriving by a longer route.1 A plant that assembles Chinese parts under a cheaper flag has changed its address and kept its dependency.

Any line that clears at only one of them was rented from a trade lawyer you have never met.

So run the arithmetic that survives Washington. Take last quarter’s landed cost and price it again at 10 percent, at 12.5, and at 20, the three numbers you have already lived through. Any line that clears at only one of them was rented from a trade lawyer you have never met.

What clears at all three belongs to you: the yield your line holds on a bad week, the tooling your engineers change over in a single shift, the customer who calls you before he calls procurement.

Then the harder half. Between today and the day you sign or walk away from that Binh Duong lease, the quality of the decision is the only item on the page still up to you, and contempt for the people who repriced you is the one input that will spoil it at no charge.

Epictetus taught at Nicopolis for forty years and never got the peninsula back.

Build the part of this that nobody in Washington has to approve.

  1. On tariffs alone the 2022 move still pays. Honigman’s alert puts China’s aggregate at 37.5 percent once the new duty stacks on the older 25, against Vietnam’s 12.5. The move was right, and it was still never yours, and a founder who cannot hold those two thoughts at once will place the same bet again on a number that has changed three times since he last checked it. ↩
