It's about time someone stops Americans from buying gasoline and plasma tvs on credit cards. If all the gasoline that has been paid for on credit cards that were not repaid in full the next month instead would have had to have been paid for in cash, Americans likely would have used 30% less oil in the last few months instead of 1% less.
Now if only China would lower Uncle Sam's credit limit. Then maybe we could have a sustainable economic future.
