I don't disagree -- I definitely struggle with this. The problem we are solving shouldn't exist. We should live in an society where people with equal incomes should have equal access to credit.

The reality is though that intergenerational wealth transfer are the primary way people acquire the necessary equity to buy homes (they get help from Mom and Dad). So I think you need both... both higher incomes, and mechanisms that create intermediary stages being renting and owning.

And on being a stretch, don't disagree. I feel the incentive is to be provocative beyond reasonableness, so apologize for that! Public schools in America are suffering death from a thousand cuts. I will tell you though that when urban school turnover (largely as a result of rising housing costs) is now up to 25%/year... it becomes your primary issue pretty fast.
