Thirty(ish) years later we have an insidious industry that has saturated US culture with the poison of unsecured credit. They set up stands at colleges, snaring college freshmen with offers of free tee-shirts. They sponsor educational curriculums in grade schools advocating the use of credit cards. They even kick money to toy makers to include a little "Visa" or "Mastercard" with their products. They lobby Congress to pass laws making it harder for people who've dug themselves into a hole to include credit card debt in bankruptcy.
Credit is not necessary for modern living, despite the propaganda that permeates every piece of media to which we have access. I know this because 18 years ago I was that ignorant kid that wanted a free teeshirt. Ten years ago I quit using credit as a means of purchase, and six years ago I made my last monthly payment (with the notable exception of student loans, which is a rant for another day).
