First world nations can't default. Stop listening to the fear-mongering bullshit that a certain part of your media likes to propagate.
You're wrong, as evidenced by the default of Greece, Spain, Portugal, and Ireland which has contributed to the almost complete meltdown of their economies.
Basically, the government doesn't take in enough money for all the programs it runs. So to make up for the gap in revenues and what is actually required, they issue what are called bonds. For the most part, these are only worth between 50 and a couple hundred dollars and are mostly bought by your average citizen. Now there are also a type that are worth much more than that and are bought up by other countries for the most part. Now, if we were to default on our loans this would make the US's credit score go down, thus showing potential investers that the US is a less than secure investment, thus driving up the interest rates we pay to those countries that have purchased the bonds. So really, it means the the government will either not have as much money because other entities aren't buying our bonds, or the government is having pay even more in interest due to the lowered credit rating.
There are other things at work, but that is a basic explanation of why a default would be bad.
