On the other thread I was embarrassed to confess that I used to travel with as much as $3000 in my socks (apparently that means I was either stupid or a criminal

). It was because I didn't qualify for a credit card and banks weren't issuing POS cards or ATM cards at that time.
I have never had a credit card because I've never had a good credit score because I've never had a credit card.
At the time I was working as a loan officer in The Pentagon Federal Credit Union and it was helpful, when I had to turn down a loan application, to be able to tell the member that it wasn't personal, I didn't qualify either. To get a loan you need to show
ability to pay (regular income for three years) and
willingness to pay and that's proven by getting a loan and making regular payments on time.
I've managed to buy furniture, cars, and houses without credit and over the years I've saved many thousands of dollars by never once paying a finance charge.
