And if you can't even afford to prioritize your family at such little cost to your work, then I think it's also pretty easy to assert that the world of the family will continually be worse off. Unless you actually cure cancer next year, collect your $1billion and quit your job to focus on your family from then on.
It's much more likely you're going to continually prioritize trivial work events (or in this scenario, non-events) over important family ones.
