What is "fairly and equitably"? If I choose to live in the most expensive metro area in the country, have ten kids, and then kill my wife so there's no one else

What is "fairly and equitably"? If I choose to live in the most expensive metro area in the country, have ten kids, and then kill my wife so there's no one else to help support them, is it my employer's fault I'm struggling? At what point do people's situations stop being other people's fault?
