Then you should read more closely. (Sorry, I say what I honestly feel.)
I think the comment you extract in the second to last sentence of your post is much closer to what OP is arguing. "It's not for me, but who am I to tell you that you can't reach for that brass ring?" If you read it in that light, from the perspective that free choice is a good thing, the argument doesn't "fall flat on its face".
>>There is no choice if that is the culture of the company or even, as it seems in this case, the country.<<
This would be true, except such countries don't exist. There is always a choice, even in places with notoriously bad working conditions (China, India, Vietnam, etc.) This culture may exist in some companies, but luckily, in more free market systems, most industries aren't controlled by one or two companies. To wit, even in the legal field in the U.S., there are many positions available that only require 40 hour workweeks.
