Do Americans work too hard?

So I was looking through different articles the other day and found this one:

U.S. workers: World's most productive

In the article it states -

"The average U.S. worker produces $63,885 of wealth per year, more than their counterparts in all other countries, the International Labor Organization said in its report. Ireland comes in second at $55,986, followed by Luxembourg at $55,641, Belgium at $55,235 and France at $54,609."

A little bit further on in the article it points out the fact that -

The U.S. employee put in an average 1,804 hours of work in 2006, the report said. That compared with 1,407.1 hours for the Norwegian worker and 1,564.4 for the French.

Not only do we create the most wealth we work almost 300 hours more on average than other country. I don't know about you, But I think I deserve a longer lunch break...
