following your logic about the drinking glass example, does that mean that in the world more drinking glasses get broken than forged? this can't be true because we would run out of glasses

Good question

No I would not conclude this. Because still to break a glass, someone needs to produce one for sure.

This example was only to showcase, that it is true that many operations have unequal efforts.

It is rarely to have reversible operations: With hydro turbines, you can pump up some water. And when generating energy with the same water almost the same amount of electric energy is gained again. This would be a counter example.
