As far as I can tell from the "snail mail" that I have received the past few years it looks like the insurance companies/medical field and credit card companies have been keeping them in business.
Use to be not a day went by that either me, my wife or one of my kids was getting an offer for a new credit card but that has dwindled down to about two a week now.
As far as the insurance companies it still seems like I get the same thing mailed to me at least three times for every claim filed. Talk about inefficient. Only the U.S. government generates more mail than these guys.
