I don't know what you are arguing. Do you believe that there will never be a situation where in a startup employers can spend more than 10+ hours of productive work in a day? I don't know why you are talking as if I didn't completely agree, and already said so, that demand 8+ hours of high quality mental work is counterproductive over long periods of time. My point remains that German labor laws make startups very hard to do. Not that I believe that you should work 10 hours a day over months, but in a startup there might very well be a situation where you can spend 12 hours effectively, which would be a violation of labor laws.
