it drives Americans to use more credit.
It was pointed out to me recently that this tendency towards credit that is really 'built-in' to the rules in our society, would probably end up doing us in one day. Sometimes you don't even think about it. I recall once, shortly after the onset of the financial unpleasantness that began in 2008, I was at an airport trying to rent a car. I thought, "Hey...I'd better start practicing what I preach!" So I whipped out a simple debit card, with more money behind it than the value of the car I was renting. "Nope...we don't accept debit...only credit". I thought, "That's a little strange...no wonder the financial system is taking a crap." I didn't have a lot of time, so I just did the credit card thing.
Point is, there are a large number of places out there that will not allow you to do business with them unless you are willing to go into debt, for however brief a period of time. When you consider the size of the US and the number of transactions being made every day...that's a little concerning.
