Regarding your childcare example: while in theory interesting, it is not a good real world example, I definitely don’t think “the same amount of work is done” - we need to transfer to our locations, this will cost money and time - who takes care of the children in the meantime? - watching someone else’s kids is quite a task, if they’re not yours chances are very high it won’t be smooth So, chances are quite high that the amount of work will be quite different than watching your own kids
