Mortgages are sold by people in a dual advisor/salesperson role, just like auto mechanics (and doctors and plumbers...). Non-predatory lenders give people reasonable advice about what kind of mortgage people can afford, just like an honest auto mechanic gives reasonable advice to people on what repairs are necessary and don't suggest unnecessary services or repairs.

Just as sketchy auto mechanics who try to overcharge for repairs or encourage a customer to have entirely unnecessary service or repairs done, predatory lenders knowingly push people to purchase mortgage products that they cannot afford.

You can't on one hand hold people who make bad money decisions unaccountable and at the same time say they should have access to all the high risk opportunities.

It has to be one or the other.
