The only way to change culture is through law. Not at all. For gay marriage or pot legalization, large shifts in public opinion have preceded changes to laws.

If it's legal to work longer hours people will, and everyone else will do so to compete with them. The Moloch post is excellent, but it doesn't really apply here. Productivity isn't a zero sum game; unless you're in a dysfunctional stack ranking environment like Microsoft used to have, being more productive doesn't hurt your coworkers. And for tech workers in particular, it's impossible to prevent you from working "off the clock" in your spare time. Yet people generally don't, probably because as others have noted just adding hours doesn't actually make you more productive.
