not all things.

Things that can scale are things that have a non-linear scaling production output vs input. For the LCDs (and semi-conductors), the area of the output is squared, if you increased the size of the production by a linear amount (let's say, the glass width). But the work required is not quadrupled!

Things that are linear in scaling - e.g., a burger cooked, does not scale the same way (at least, not for a McDonalds burger) - it's a one to-one, even if you tried to make it scale up by having more cooks/more machines etc. Cars, to a similar degree, but the fixed cost of a car factory/assembly line vastly out weight the lack of scaling i suppose, and so cars did get cheaper but not from the scaling manufacturing, but from cheaper components, and more automated steps etc.
