I'm actually a Swedish business owner (me and co-owner) doing 30 hour weeks. One of our main goals of starting our digital consultancy was to work less but receive same or better pay. It works well for us. We're at least as productive as we were as employees.

The main difference being we cut out "fika" - this was easily 60 minutes per day at our old work place - and dropped all private web lurking from the work days. We just decided we didn't need all that downtime from doing work during days, we'd rather spend it at home.

Clients are pleased with the work, I get to both drop and pickup up my kids everyday. In Sweden, if you've got web dev skills, this is very doable.

I believe in it on a bigger scale for worker happiness sake and really hope we'll get there soon.
