I think the interpretation of this is off. Less tired and less stressed translates to "more time with their parents".
Or perhaps more "quality" time. If a parent is too stressed or tired to give their full attention and engaging with a child, then this really does translate to wanting parents to work less.
I think this is ignoring the many people that grew up poor, where your parents weren't writing emails or stressed about work. But rather weren't constantly stressed about not paying the bills putting food on the table, or keeping the heat on.
