Over the past two centuries, 51 out of 52 countries that reached sovereign debt levels of 130% of GDP ended up "defaulting" [within 0 to 15 years], either through devaluation, inflation, restructuring, or outright nominal default.
US debt to GDP March 2021: 132 %
Uh oh… that doesn’t bode well for ye olde USD 
It's different. Usd is the world currency of exchange. Pesos, Bulivars etc... aren't.
It will only defult when every nation stop trading in dollars. Untill then, they will always print more money withou consequences for themselves.
That only eliminates the default through outright nominal default. If you read carefully, other possibilities for default are mentioned (devaluation, inflation, restructuring) which are very likely for the US.
Don’t be the “this time is different” guy
