This. It doesn't have a dollar value, because it will vary based on circumstances and cost of living.
Generally, I think of it as meaning that they don't have to carefully budget in order to have their basic needs and wants met. Doesn't mean they have a yacht or take exotic vacations every year, but they don't have to scrimp and save or watch bank account balances like a hawk.
