It's funny how you assume there'a choice. Unemployment in Europe as a whole (including Eastern Europe) is ~20%. Depends on what/when exactly of course but it is. Government (non-productive by definition, by which I mean they don't add value, not that they're not useful) is easily half of the remainder. So Europe has 40% value-adding employees among the working age population, which is about half the total population, or 20%.
In America it's actually better, close to 30%. Everywhere else it's much worse. In the Middle East, Africa, most of Asia it's at most 10%, and usually less than half that.
That means that you could, not in 50 years when the robots have taken over, TODAY, kill 85% of the population and the net effect on the world would be ... nothing. GDP wouldn't drop by so much as a dollar. Today, 85% of all humans alive are useless for the economy (some are school children and will become useful, but you could assume that to be ~10% and you wouldn't be far off the mark).
So for doing everything we do today, and for guaranteeing the future, we need around 25% of the human race. Everyone else is economically useless.
Note that this figure has been dropping for 40%, and has been for essentially all of history, with only short blips where more of the human race is actually useful (like the 30 or so post-WWII years). Even 15% economically useful population, historically speaking, is actually high, not low. What I mean to say is that the neutral expectation should be that that number is going to drop, not rise.
So: no, a company should not ever be able to restructure. Every month, every day, every second we can keep that number up by even a small amount gives use one more month, one more day, one more second of the society we currently have, where people are actually somewhat useful. The alternative, if you think it through, I'm sure you'll see, is war.
Or to put it another way: we need these people to have a job much more than we need a few extra dollars of GDP.
