lol NO- Wtf are you talking about? Who would use a credit card when the entire balance had to be paid in full every month. You might as well carry cash with you at all times- nobody would use it.
I have an Amex card- Another way they make money is by charging huge interest rates on your monthly balance- much higher than visa or MC.
Amex isn't a credit card, ...it is a "charge card", ...
without any preset spending limit.
Charges are approved based on your previous history and ability to pay. If you regularly run up $10 - $15K a month,
then pay the balance in full at the end of each month, chances are your charges to the card won't be declined.
And they'll send you a nice pretty Platinum card that you can flash at nightclubs... and pull serious tail.

If you charge $350 on the card in any given month, ...and fail to pay the balance in full on it's due date,
...you might not wanna attempt using the card when out for dinner on a date, ...unless you like embarassment

In recent years Amex has made credit cards available for those who keep monthly balances.
