Considering that a 30 year loan means paying 3X for any product, a banker disaster to promote lending profits makes sense.
Urban renewal was irresistible to the ruling scum. Once healthy cities were broken up by WASP-Jew evil-doing, ethnic communities had to flee the cities to the suburbs and get 30 year loans for new homes.
This was on a scale of trillions of dollars from the 1970s and 1980's on. The post-war "boom" had to continue or else the whole scam would collapse.
