If your mailbox is like mine, you can't find your mail through all of the credit card acceptance notices. Believe me, there is plenty of credit to go around.
At loan-shark rates, sure there is plenty of credit to go around. The amount of money they can make per sucker gives every incentive to saturate US mail with the mailings. It's not the credit that is lacking but the ability to borrow. Many will only leverage themselves so far even if credit is available.
