"But it seems you also have a misconception about how human productivity works if you think 60 hours a week (you didn't say this, I'm just guessing based on your tone) will give you a more productive year than 35 or 40 hours."
No, I didn't say that and you shouldn't read that into what I was saying. I was specifically comparing the situation for startups that I've seen having worked in them in the UK, US and France.
And I am specifically NOT wishing to comment on the moral or political motivations for the work environment in those countries. Each country has developed its own history and culture which I do not seek to criticize. My original point was that I do not believe France is a good place for startups. That is all.
