So get rid of all of that, and I think you will find the problem remains. You can get paid in cash with no loans and STILL blow your entire paycheck in 2 days. Or you can get paid in cash and STILL save 50% of it in a bank and live in your means.
Not that we should not touch predatory lending. But so much of our economy is built on advertising and stuff, just shutting off the loan tap will not fix the problem.
