Earlier quoted context omitted.
I'm 46. I've never had a credit card. I have a bank account and a debit card. If I can't afford something, I don't buy it. You can just opt out of using credit cards.
Honorable but foolish. You could effectively get a discount and still use it the same way as your debit card.
The entire credit card industry is set up to squeeze out as much profit from people as possible. They offer discounts as an incentive, but it is a huge trap that many, many people fall into. I'm not interested in risk. I'm interested in simplicity.
It's participating in the credit card industry that is foolish.
