I think we're on different wavelengths, since I actually agree with what you say.
What I'm trying to do is refute the Broken Window Fallacy, which says that if you go around breaking windows you'll benefit the economy, by creating jobs fixing windows. But what you've done is made owning windows more expensive, since they periodically need to be replaced. And the standard of living drops a little, because you're wasting resources fixing windows that you could be using for something else.
Making a window factory more efficient is the same as not breaking windows. You've reduced the resources needed to own a window. The window fixers will complain that you're hurting the economy, by removing window-fixing jobs. But people will have additional resources that they can spend on something useful. This might be bigger windows, but it could be better healthcare, police, etc.
The only way for jobs to actually be lost is if people started working fewer hours, because they are free of their window-fixing burden. But, I can't see that happening in response to Tesla's robotic factory?
Whither now your broken economic system that requires unlimited growth?
I didn't say it was a good or sustainable system.
