I agree with Malissa that it depends on role, industry but I also think that it depends on your definition of work-life balance. Everyone has different life circumstances and while I think it's a fair question (i.e. the more you make, typically the more responsibility you have at work), it possibly frames income and time as resolute opposites where that may not be entirely accurate. For example, I would ask yourself if you've considered framing work-life balance in terms of what is controllable and not in your life. The more control you have over your working conditions, hours, family/home/personal life (for whatever reason -- be it the employer, household/extended family support), the more you will feel that work-life balance is achievable because you can schedule and move things around as needed, even if you have to work quite hard or even objectively longer hours.
