I don't see how it can be true that rising wages results in no net gain if vendors aren't increasing costs disproportionally to their inputs. A simple model of product cost is labor costs + "other things" like materials, retail overhead, etc, multiplied by some profit margin. If worker wages double, only the labor costs have doubled. The non-zero "other things" have not doubled (they may increase, but you can apply this argument recursively until you get to the base case), so the ultimate price cannot have increased by the same proportion. Thus, all workers should have a net gain.

one way this can hold everyones wages have increased so other inputs can also increase

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.

All of those things as far as I can tell can rise with wage increases as they will get more use? Except for Fixed Tariffs
