I think the number of holidays are too many in Germany or is it common across Europe?
Same in Italy and, as far as I know, also France.
In Ireland it's about 4 weeks, if memory helps
To answer the question though, I think Germany's economy would be stronger (or even stronger) if they cut back on vacation time. What do you think?
People on vacation create good business for tourism, for example. Also, one could argue that if people are well rested and recharged from the holiday they are more productive when they go back to work.
