This is the crux of a state mandated shorter work week.
In Australia, the default is between 35 and 40 hours, 5 days a week.
Some people work more hours, some fewer. A proposal to change the standard wouldn't affect that arrangement.
People who enjoy working longer hours, say for a pursuit they enjoy or endorse, or like you to build up their own wealth at a much faster rate, likely wouldn't be affected by such a policy change.
I do hope you're not suggesting that your personal preferences should inform proposed policy changes like this?
