I would agree with that, and there are different ways to do it. One of the things that I do sometimes is look south of the border where they have joint tax returns, where a family can in theory file a tax return and report all of their income, rather than here where you have a potentially high-income earner, a low-income earner, and a big inequality when you compare them to another family that has the same income with equal amounts of income.
