Not that I'd advocate dishonesty, not credit card debt, but the point of paying off one credit card with another can be taken to a ridiculous
conclusion. It's based on the fact that credit cards essentially offer unsecured loans
Firstly, one needs to make sure you have enough credit cards. This can be achieved by applying for any credit card that a company offers you.
Secondly, it's advisable to start with a good credit rating. This will help convince the companies that they want to give you a card, and also lots of credit.
All one has to do then, is run up a bill on one and the following month, pay it off with a different one. Keep repeating this process and you will find that you have an excellent credit rating, being a prompt payer, and therefore the companies are falling over themselves to give you more credit. Result, you keep spending other peoples money, and never have to pay it back.
All one has to do then, is to die before they work out that you haven't ever paid back a penny :)
