Are you immortal? Do you have an income vastly higher than the servicing cost of that debt? Do you owe the large a majority of that debt to yourself? Are you able to, if push came to shove, tell your external creditors to go fuck themselves and dare them to so much as try to collect on the debt you don’t feel like paying? If you can’t answer “yes” to all these questions, you aren’t the US and have a debt situation that has absolutely nothing in common with the US debt.
