I think it's important to make a distinction between working hard for work's sake and working hard because you really believe in what you're doing. The concept of hard work that most people who frown upon it in the US have is likely the former and I would tend to agree with them. Mindlessly doing menial tasks but putting in "18 hour days" is not something to be admired. That being said, a culture that encourages people to dedicate a lot of time to a company, a cause, or an idea if they like it or believe in it is certainly worth fostering. If this is the kind of hard work that Sam talks about as being looked down upon in the US, then that is indeed troubling and we should try to correct that perception.
