"The other part is that there is no inherent difference between nations in how well they can potentially manufacture something"

You sure?

I'm sure at least in a geopgraphic sense. I know Africans aren't going to make processors and whatnot

It's different in the primary sector

So what about minimum wage laws? Country A has them at 15Y and country B has the minimum wage at 5Y

Both countries produce cars and jobs making cars are all minimum wage

cetrius paribus which one is better?

I don't like minimum wage laws because they don't actually adress the issue of oversupply of labour

not relevant

"oversupply of labour"

No such thing

People making better wages off of the car industry is better. I'm aware that it'll make cars marginally more expensive

And yes there is oversupply of labour

That's a subjective term your using

not relevant

Though it's a subjective category I think it's fair to say there are too many low wage/low skill workers

so we have established some countries produce goods cheaper than others

so the theory is correct

In the moment

It doesn't tell you about peotential output

What the fuck does that have to do with anything now

It really isn't complicated

The point is output per input not just output

opportunity cost

It's all opportunity cost

country A produces more Y with less Z than B

so it makes sense for them to make it

Yeah in a given moment

apply this to two commodities

then you can have to countries, one can produce both goods better but its about what you are producing at the expense of

I'm not sure you understand the logical law

A factory doesn't take inherently more Z to produce B depending on which country it's in

That's entirely variable

WHAT

Industrial techniques and the like advance over time as long as you have an industry to begin with

It's so simple, do countries produce goods at differing opportunity costs? Yes or no?

Mate I think you should stop digging yourself a hole here

Just watch this

Not inherently. There's only certain commodities which actually have an inherently differing opportunity cost depending on the country
Fracking is more costly than extracting in Saudi Arabia for example. Fields differ inherently in what climates they are in, how fertile they are etc.
Factories almost entirely depend on technical expertise or cheap labour

The advantage free trade offers you is that you get immediate gratification by getting stuff cheaper
