Yes, I mentioned that already. The argument applies recursively, and the total increase is always less than the wage increase as long as there is some cost somewhere in the supply chain that is not responsive to wage increase. This could be land, or raw materials cost, or fixed tariffs, or fuel costs, compute, infrastructure, doesn't matter. The whole thing is a linear function, so doubling is the max increase that can occur, and any costs that don't respond must lower the ultimate increase.
