The problem isn't that you're an existing homeowner. The problem is housing is exorbitant.

Everyone has to pay out of the nose for housing. The only difference is that you have an asset that has appreciated significantly, and in a way you're indirectly receiving dividends from it in the form of affordable mortgage payments.

But if you didn't have that house, you'd be in an even worse spot.
