So big deal, the federal government inefficiently mails an additional page. I've seen worse.
Big deal? How would you like to process 100 million+ forms and then be told another 100 million will need to be processed. I think you underestimate the logistics and the additional labor needed not only to process but to have workers in the field needing to collect not just one form but going back to collect another if the household does not respond. Then you have to cross reference....a complete nightmare and a recipe for disaster.
