How has the U.S. demonstrated irresponsibility? It is able to borrow at favorable rates from people that do not have a lot of recourse in the case of default.Good try at waving a red flag.
I am saying that responsible borrowers don't have a problem with loans.
The American people (through the people they regularly reelect) have not demonstrated responsible borrowing behavior.
Until they do, it is time to clamp some restrictions on the enabling behavior. Once America decides to behave as an adult fiscally, you can drop the ammendment. Or not.
