Saying employers don't want it is kind of stating the obvious. Of cause the employer tries to extract as much value as possible, while most discussion in this thread seems centered around improving quality of live of employees. So looking at only one side of the labor market doesn't really help. The more interesting question is employees make deals without it. Is it actually true to say there is an market equilibrium at 40 hours? I'm no expert, but 40h seems heavily reinforced by regulation (FLSA comes up on search). Without government intervention, I'd not see much stopping a race to the bottom, at least for a significant part of the job market. I wonder if less wealth inequality would give more leverage to the average citizen, enough so that this additional bargaining power would make a significant difference on the job market. Influences like that might explain the systems trends over longer time periods...
