I remember Reagan TV ads where he was talking about 1T in national debt... being a LOT.... so without looking, it was around that in '80. College students didn't have CCs back then. A dozen years later, the national debt was around 5T, and the industry had the American comsumers addicted to debt ... just like a junkie. Debt... the opiate of the masses.
I think it was the trickle down theory ... and Americans pissed on their own legs
