economy - Do the golden weeks make sense?

The question whether the system of the three golden weeks makes sense is as old as the golden weeks themselves. In 1999 suddenly the Chinese got in stead of one holiday week three at fixed times. The original reason: our people have no time to spend the money when they never have a holiday. That was a big success: spending went up dramatically and although that effect has a bit leveled out, you can still see it makes sense when you dare to walk around during those holidays.
The systems had many disadvantages, as Marc van der Chijs points out, especially for foreign companies who have to deal with customers and parent organizations who are not free during these weeks. Micah Sittig actually quotes a not-so-high officials of the tourism department who tells the compulsory holidays will be over soon. For tourism that would make sense, since now all the investments in tourism (look for example at Hainan) have to be earned back in three weeks time, and it would be better to spread that over the year.
Still, it is not going to happen, a group of my friends already concluded during a heated debate in 2004:

Reshuffling the golden weeks would create another problems, we analyzed. Looking at our friends and staff, we estimated that a larger number would not go on a holiday, when they could decide themselves. The Golden Weeks forces them not to work, in most cases people would otherwise rather go to work.
