because sometimes it's a good idea to help direct such changes. Things like discussion, detailed planning, and more discussion are a good thing.
You think we have a national 40 hour work week because it magically appeared one day?
Hunter/Gatherer societies work an average 15-20 hours a week. The downside is that they have much more volitile food sourcees, limited division of labor (and therefor lower quality goods in many case; namely housing).
We have traded our free time for better housing, running water, and medical care.
How much are those benefits worth to you? I'd say slightly less than 10 more hours per week. Not an additional 25, though, as the average American work-week suggests.
So I put forth that we work out a 30 hour work-week plan for the US, and remember how to share in this country (instead of everyone having their own TV's, their own PS2's their own cars, etc,etc,etc,etc,etc...).
Currently, I work two jobs, and own a side buisness. I also volunteer my time weekly, and I tend to have a 60 hour work week. I do, however, have flexable work hours for my full-time position, so my schedule is maintainable (I don't have to wake up at 5AM everyday

)
