I agree that Credit Cards are abused by too many people. So are computers, cell phones, and many othet tools of modern society. If you choose to opt out of the credit system, you will impair the quality of your life. Many things rely on your credit scores; from getting a mortgage, auto insurance, home owners insurance, to name a few. Manual Mortgage Underwriting is available on some mortgage products, but not all. The convenience of making a hotel reservation, and booking an airplane flight on line are good things. Credit Cards provide limited liability to you in case of fraud (ID theft), whereas a crook who gains access to your debit card and PIN # can drain your account. Automobile, electricity, and credit all carry inherent risks, but used prudently, the benefits outweigh those risks.
