I'm in Japan now and Japan is still like this. Actually, a lot of SE Asia is like this - Korea, HK. When I talk to people about this they even admit it. They realise they are goofing off a lot of the day because they know they have to stay late so there is little incentive to be productive.

I believe that people can only work productively for a set amount per day and keeping people at work after that doesn't lead to any more work being done.

In general what you are saying is true, but its not the general public your must fear in the competition.

Its always the exceptional guy who is going to win the prize any day. And that is why people always run into exceptionally productive people and don't find it easy to compete with them. Multiply this with the drive and energy which keeps them productive over time and suddenly things get very difficult.

For most people 5 hours of productive work will see them by, but you should not expect that to be sufficient to be the best or to be sufficient enough to beat the best. For that you will have to do something extra.
